Powerdynamo for JAWA 634 and CZ 471

If you can install and time a stock ignition and possess basic mechanical skills, you can install a Powerdynamo! If you never have worked on your ignition, better have it done by someone who knows.
Powerdynamo can not monitor the compliance to those instructions, nor the conditions and methods of installation, operation, usage and maintenance of the system. Improper installation may result in damage to property and possibly even bodily injury. Therefore we assume no responsibility for loss, damage or cost which result from, or are in any way related to, incorrect installation, improper operation, or incorrect use and maintenance. We reserve the right to make changes to the product, technical data or assembly and operating instructions without prior notice.
IMPORTANT:	Please read these instructions fully and carefully before starting work on your motorcycle Please bear in mind that any modification of the material as well as own repair attempts which have not been agreed with Powerdynamo may result in a loss of warranty. Do not cut off wires. This leads to a loss of reverse polarity protection and often results in damage to electronics. Also, please take note of the information provided on the information page for this system. Check that what you have bought really corresponds to the motorcycle you have. Wrong ignition settings may damage your engine and even hurt you during kickstart (violent kickbacks). Be careful during the first test runs. If needed change settings to safer values (less advance). During assembly check carefully that the rotor (flywheel) does not touch the stator coils or anything else, which may happen due to various circumstances and lead to severe damage.
	Designated use This system is designated to replace stock dynamo/alternator & ignition systems in vintage and classic motorcycles whose engine characteristics have not been modified aftermarket. This system is not a tuning system and it will not bring significant increases in engine output. It does however significantly enhance roadworthiness and comfort by offering better lighting, better function of side indicators and horn and, compared with the aging stock systems, increased reliability. As our system does not tamper with engine characteristics it does not increase emission of gaseous pollutants and noise. In most cases emission of pollutants should even be reduced due to better combustion. If used as designated the system therefore will not normally infringe the existing legal status of the motorcycle (this statement is valid for Germany, for other countries, please check locally against your road licensing regulations). This system is not suitable for use in competition events. If used other than the designated way, warranty will be voided and it might well be that you do not obtain the desired results or, worst you loose legal roadworthiness. The charging system is only suitable for use with rechargable 12V (6V systems 6V) lead-acid batteries with liquide electrolyte or sealed lead-acid batteries, AGM, Gel. It is not suitable for use with nickel-cadmium, nickel-metal-hydride, lithium-ion or any other types of recharchable or non rechargable batteries. This is a replacement system and not a copy of the stock material. The parts in this system therefore look different and might fit differently (notably ignition coil and regulator) requiring some adaptation by you.
	During assembly imperatively start with assy of engine based parts to see that those really fit before you start fitting the external parts. In many cases customers assemble those first and thereby often modify them in breach of warranty which renders them unfit for renewed sale. Replacing old ignition systems is not a matter of taking something from a supermarket shelf as there have been very many types, versions and possibly unknown aftermarket modifications which harbour plenty of room for error.
	Our systems are NOT tested for use with third party electronic devices (such as GPS, mobile phones, LED lighting etc)and may cause damage to such parts. Possibly existing electronic tachometers will not work with the new system. Read our information for suitable solutions. Possibly existing safety switches and electronic valve controls are not supported. It might be that your motorcycle was originally equipped with an ignition that did limit top speed for legal reasons. The new system does not have such a facility, so check your legal situation beforehand.
	If you have no expertise for the installation have it done by an expert or at a specialist's workshop. Improper installation may damage the new system and your motorcycle, possibly even lead to bodily harm.
	Before you order a system, please check whether a puller tool for the new rotor is included in the kit. If not, better order it at the same time. You might want to order light bulbs, fuse, horn, flasher unit etc. Never use anything other than the recommended puller tool to pull the new rotor again. Damage to the rotor as a result of use of other tools or methods is not covered by warranty.
	The rotor is sensible to blows (including during transport). Before assembly, please always check for damage (on rotor without magnet plastification try to push the magnets aside with your fingers). After impact the glued in magnets might have broken loose, sticking to the rotor solely by magnetic force, so that one does not notice right away. During engine run the damage would be considerable. Before placing the rotor onto the engine, please make sure that its magnets have not collected any metal objects such as small screws, nuts and washers. That equally would lead to severe damage.
	If you have access to the Internet, best view those instructions online. You get larger and better pictures by clicking onto them and possibly updated information. System list at http://www.powerdynamo.biz

	You should have received those parts: stator coil on adapter and with sensor rotor (flywheel) regulator/rectifier twin ignition coil coil holder bracket HT cable switch off relay fastening screws for stator assembly and ignition coil battery cables
Please note that the stator coil is only loosely mounted to the base plate at time of delivery as you will have to disengage it during assembly (otherwise you will not get the fastening screws to the crank case fitted). Please observe further that the sensor (pickup) is only loosely mounted by us, as you have to set its gap. Tighten the screws carefully after setting.

	To pull the new rotor again, you will need a puller tool M27x1,25 (part-no.: 99 99 799 00 -Not provided!-). Note: Never use a claw puller, a hammer or any other device, that will shake the magnets off.
	To pull the old rotor, you will need a puller tool M8 (part-no.: 70 80 899 90 -Not provided!-).

Notes on wiring: Experience shows that in the course of time nearly every motorcycle undergoes changes to its wiring. As a result, wire colors and wires themselves on your bike might differ to those we describe. In case of doubt, please consult your the original wiring diagram. Note that there have been very man versions of JAWA 634, differing also in wiring.

Disconnect your battery and take it out of the motorcycle. Note that you now install a 12 volt system, so you will either need a 12 volt battery or you use the option of driving without. You will in any case have to replace all light bulbs to 12 volt ones. The horn may stay at 6 volts. For driving without battery, please observe our respective information. Decide what sort of switch off method you want to install. There are two options, each with its advantages and disadvantages. We have pre-assembled the relay option as this will permit switch on/off by key as before.
relay method (supplied as standard) advantage: This option will allow you to use your ignition switch as before. Nothing changes disadvantage: You cannot normally ride without a working battery. In certain cases it can however work without, depending on speed of kickstarter (see info here). Should the battery brake down on the road, pull the brown wire bringing earth to the relay so that it has no longer contact to earth and you are on the go again.
kill switch method advantage: You may drive without battery, a plus for bikes driven only rarely. Disadvantage: the bike may be started without key at any time (Unless you add some extra breaker switch) Best solution is to use and rewire the existing stop-switch at the RH side of the handlebar. (in very first versions there was no such switch and you will have to install some additional kill switch at the handlebar if driving without battery) The operation of this switch will however be reversed, where before was ON is now OFF and vise versa. This switch in stock wiring did break the supply of voltage to the ignition coils. Now you rewire the switch so that it connects the blue wire of the new ignition coil to ground when in ON position (which is now OFF for this ignition!). When switched to OFF, the switch is open, disconnects therefore the blue ignition coil wire from ground and the system is ready to operate. For background to switch on/off of this powerdynamo system see knowledgebase here.

	Disconnect all wires from your old dynamo, regulator and the ignition coils and remove those parts. You may pull your old rotor from the crank shaft by means of a puller screw M8x90. Check whether the neutral gear wire had been running through the pieces of harness you are going to remove. If so, if will get removed and you will have to install a new one.
Pay attention to the wire that did run from pin 30 of the main switch to terminal B of the old regulator. This wire will again be needed and connected to the red of the new regulator (input of voltage from new magneto) Pay attention to the wire that went to terminal D of the old regulator into the lamp housing and there to the charge control bulb. Also further on used (unless you drive without battery) to operate the control light (connect it to green/red of new regulator) Pay attention to the wire running from main switch to the old ignition coils. It will be used too and get connected to the black of the new relay (so used, otherwise the stock wire remains (insulated!) idle. Remove wires running from the contact breakers to the old ignition coils. They will not be needed any more.

Check at the new base plate the position of the sensor (pick-up) at the rectangular plate. There are 2 possible mounting positions.
	For the 634 the sensor will be positioned to the RH side (we pre-assemble this as default). For the 471 it does not matter in what position you place the sensor, as timing is achieved differently. (see below)

	Unscrew the stator coil from the base plate and lift it a little away from it so that you can access the mounting holes. Take care not to damage the paint insulation of the coil. Identify the correct fastening holes at the base plate as seen here. There are 2 sets of them, one used for all JAWA models.

	Put the base plate (consisting of the outer steel ring and the inner aluminium plate) into the place of your old generator. The sensor should show into a 10 o'clock position, the stator coil will hang loosely. Make sure to use the right set of fastening holes and screw the plate with the help of the 2 countersunk screws M6x40.

	Put the stator coil back onto the plate, take care not the damage the wires. Make sure that the inner opening of the stator unit slots evenly over the elevated fixing rim of the base plate - otherwise the coil will sit lopsided and will tough the rotor, damaging it. Screw the coil down with the 3 hex screws M6x30 and tighten.

	Under no circumstances effect mechanical changes on your engine casing in order to fit the system (save for pulling or breaking the pin at the stator base). Do not try to assemble the new stator without the steel ring, even if you think temporarily that fitment may only be achieved that way. This comes from a wrong assumption that the stator should be fitted right down to the bottom of the engine casing. The new system will sit, as the old one did, in the recesses a little higher up.

	Place the rotor drum onto the crankshaft, taking care to fit the slot onto the roller pin of the crank. Check that the rotor sits well on the shaft. It happens that a roller pin is a little to high and prevents good fitment. In that case take a little material of the roller. In CZ 471 remove the pin! This is imperative, otherwise you can not time correctly. Check further, that the rotor runs freely above the base plate. Tighten the rotor with the screw M6x40, not forgetting the supplied washer. To undo the rotor use a puller M27x1,25 (and only such!)
On the CZ471 you will have to pull the roller pin before you install the stator. No worry there, it does not have a fixing capacity, it is intended for guidance only (Info here). After installation of the stator and before placing the rotor onto the shaft, take the spark plugs out, bring any of the 2 pistons into ignition position and than place the rotor onto the shaft so that it will sit in the position as shown below.

	Turn the rotor slowly by hand and check clearance between the sensor and one of the rotor noses. This has to be ca. 0,4mm. You may adjust the gap by loosening the 2 holder screws of the sensor and shifting it a little. Do not forget to tighten the 2 holder screws of the sensor carefully. If loose, the sensor will get into contact with the rotor and will be destroyed. It is a good idea to check secure fitment from time to time.

	Mount the regulator/rectifier unit of your new Powerdynamo system at a convenient place (best same where the stock regulator had been sitting). Also fit the relay (so you use this option). Proposition is next to the battery.

	Fasten the new ignition coil to the supplied fixing clamp and screw this clamp than to the frame, using the hole where the stock coil holder had been fastened.

Connect the parts as shown in the respective wiring diagram!
For our standard DC regulator (95 22 699 06), use the wiring diagram 72xr12:
For our DC regulator with built in smooting condenser (73 00 799 50), use additional the wiring diagram reg_102:

To facilitate wire exit through the often small openings in the engine casing, the plastic plug of the generator's wiring that leads to the ignition coil have not been put onto the wire terminal. You should place the plug there only once all has been properly installed on the engine side.

Look for the ignition coil with its female plug and the three wires (red, yellow and white).

Put the provided 4-position plug housing onto this plug and insert the three wires (red, yellow and white) from the generator. Make sure that the terminals engage securely in the housing and that you connect:

red to red
yellow to yellow
white to white

Should you need (or want) to get the terminals out of the plug housing again, enter a paper clip from front next to the terminals and push the little barb aside. Than pull the wire out.

Connecting Powerdynamo alternator to lighting circuit (via regulator):

The 2 black wires running from the stator coil carry the voltage for lights, horn, flashers etc. They have nothing to do with ignition.

This voltage (something between 10 and 50 volts AC) has however to be stabilized (regulated) and for most uses rectified into direct current (DC) as it primarily is alternating current (AC).

For this we offer 2 different regulators:

Attention: Any confusion between plus and minus (with the DC versions) leads to immediate destruction of the regulator. This will not constitute a warranty case as it is negligence! One can recognize a burnt regulator mostly by its sharp smell.

Regulator type 1: with standard DC regulator (95 22 699 06), use the wiring diagram 72xr12:

The new regulator/rectifier has a compact plug with 6 positions, of which one is not used. A female plug cover fitting to this plug is delivered. Into this female plug you have to insert the following wires (which have terminals that snap into the plug):

The two black cables leading from the generator ...

... connect to pins 1/4 of the new regulator (from there equally black wires lead inside the unit). It does not matter which wire connects to which of the both terminals (1/4) as they carry alternating current.

The new brown cable with the round eye terminal ...

... connects pin 3 of the regulator unit (from there equally a brown wire goes inside the unit) with the negative pole of the battery or (in case you drive without battery) to ground (chassis).

The new red cable with the round eye terminal ...

Take care:
Wrong polarity will damage the electronics!

... connects to pin 5 of the new regulator (from there equally a red wire goes inside the unit). Here your regulated positive voltage comes out to connect to battery plus, or (in case you drive without battery) to the voltage input terminal of the main switch (ignition lock, German bikes: pin 51/30).

Make sure that you have a 16A-fuse between battery and vehicle circuitry.

The green/red wire at pin 6 of the new regulator ...

Remark:
Until November 2007 this wire has been a single wire outside the compact plug.

... is for the charge control light. You connect there the wire that formerly did run from the control light to the original regulator.

Sure that this control only functions with a battery present. Should you drive without battery but still connect the wire, you will see that the light glows even as the generator generates voltage. So without battery, do not connect it.

The charge light control function is based on a transistor switch and is an additional function. Even if that should fail, the regulator might still be in ok working condition. Simple check: have the engine running, turn lights on, disconnect the battery. If you have bright lights the unit is ok.

Regulator type 2: with DC regulator with built in smooting condenser (73 00 799 50), use additional the wiring diagram reg_102:

the 2 black (sw) wires are the AC input from the alternator (as it is AC it does not matter which black to which black)
the red (rt) wire is the 12V DC output plus
the brown (br) wire is gound, internally connected to housing

Remains the blue (sometimes blue/white) wire at the ignition coil. This is the kill (cut-off) wire.

Connected to ground - it will stop ignition!

Note:
Should you experience ignition failures, disconnect as a first measure this blue wire. In many cases that will permit you to get mobile again (particulars see: technical help)!

Switch off via separate kill switch
(when driving without battery):
The relay will not be fitted. The blue(/white) cable of the ignition coil will be connected to a kill switch, closing against ground (a button at the handlebars). Or you mount an ignition lock that has a facility to connect against ground when in OFF position.

Battery method:
Connect the brown relay wire to good ground. Lead the longer black wire from the relay to the wire that did run previously to a pin carrying voltage when the switch is on (in German bikes: pin 15) and connect it there.
Connect the blue wire from pin 30 of the relay to the blue(/white) wire at the new ignition coil.
should your battery fail on the road, just disconnect that blue wire and your bike will run again (it will now only not stop by switching off).

Relay wiring
(if used):

The brown wire with the ring terminal from pins 87a und 86 goes to ground.

The black wire from pin 85 goes to a main switch terminal carrying voltage if switched on.

In our twin outlet coils both ends of the secondary go to the spark plugs.

Typical resistance between both exits is 6.2kOhm. Both exists fire at the same time (as many twin systems do). Sparks will be polarised however at a 180 degrees difference which might manifest when you strobe it.

Ignition will only work correctly if both plug terminals are connected. You may not test one side with the other open (not sitting on the mounted spark plug). This is because (effectively) each exit uses ground from the other. That means also that both plugs are working in serial, adding resistances, so better use low resistance spark plug (resistor) sockets and make sure they are good. If in doubt, measure resistance on a hot socket (warm it up before measuring).

Is the flow from ground of one side via spark plug there, via coil, to the other spark plug and its ground interrupted you get no spark - on neither side. If you really want to test only one side, put the HT wire of the other to ground (earth it) than it will work. Sometimes a coil deprived of its ground from the other side searches for a substitute - with some solid fireworks around it to the chassis.

Screw the high tension (ignition) cable ...

Please do not use any spark amplifying cables, such as "Nology supercables" or "hot wire". This will disturb the system and possibly damage it.

... into the ignition coil and pull over the rubber seal before mounting the coil (it will be easier).

Please do use the cable arriving with the pack and not any old cable.

You will do yourself a favour to treat your bike to new spark plugs and spark plug sockets (preferably some between 0-2kOhm). Plenty of problems are to be traced back to "apparently good" (even completely "brand-new") sparks plugs, terminals and cables.
Do not use spark plugs with an intern suppression resistor. NGK (e.g.) offered such spark plugs coded with an "R" (for resistor).

Finally - and before installing the battery and before the first kickstart - please re-check carefully all connections and fitments against the wiring diagram. Do check battery and light bulbs for correct voltage (12V).

Should something not work, please consult our trouble-shooting guide on our homepage. As a first step disconnect the blue wire from the coil and re-test.

IMPORTANT: During crank shaft repair the dynamo shaft is often machined and gets shorter. The result is a rotor sitting lower, possibly touching now with its rivets the stator coil. The result is a destroyed stator and ignition failure.

	Important safety and operating information
#	Safety first! Please observe the general health and safety regulations motor vehicle repair (MVR) as well as the safety information and obligations indicated by the manufacturer of your motorcycle. The timing marks on the material are for general guidance only during first installation. Please check after assembly by suitable means (stroboscope) that settings are correct to prevent damage to the engine or possibly even your health. You alone are responsible for the installation and the correctness of settings.
#	Ignition systems generate high tension! With our material right up to 40,000 Volts! This may, if handled carelessly, not only be painful, but outrightly dangerous. Please do keep a safe distance to the electrode of your spark plug and open high tension cables. Should you need to test spark firing, hold the spark plug socket securely with some well insulating material and push it firmly to solid ground of the engine block. Never pull sparkplug caps when engine is running. Wash your vehicle only with engine at standstill and ignition off.
#	Should you have received in the kit HT cables with a fixed rubber boot(which does not contain a resistor) you might have to use spark plugs with an inbuilt resistor (or replace the cap with one containing a resistor) to comply with your local laws.
#	After installation, please check tightness of all screws, even those preinstalled. If parts get loose during run, there will be inevitably damage to the material. We pre-assemble screws only loosely.
#	Give the newly installed system a chance to work, before you start to check and test values, or what is worse apply changes to it. Our parts have been checked before delivery to you. You will not be able to check much anyway. At any rate do refrain from measuring the electronic components (such as ignition coil, regulator and advance unit). You risk severe damage to the inner electronics there. You will not get any tangible results from the operation anyway. Bear in mind that also your carburetor, your spark plugs and spark plug sockets (even if completely new) might be the reason for malfunction. The general experience with our systems is that the carburetor will have to be re-adjusted to lower settings. Should the system not start after assembly, first disconnect the blue (or blue/white) cut-off wire directly at the ignition coil (or in some cases advance unit) to eliminate any malfunction in the cut-off circuitry. Check ground connections carefully, make sure there is a good electrical connection between frame and engine block. In case of troubles, please consult our Knowledge Base first before you send off the material to us for checking
#	The spark of classic, points based ignition systems has with about 10,000 Volts comparatively little energy and looks therefore yellow and fat (which however makes it highly visible). The spark from our system is a high energy spark with up to 40,000 Volts and therefore is needle thin focused in form, and blue in colour, which makes it not so visible. Furthermore you get spark only at kick-start operated speeds and not by pushing the kick-lever down slowly with your hand (as you might get with battery based ignitions).
#	Systems using a twin outlet ignition coils have a few peculiarities. Please observe that during tests on one side, the other has either to be connected to an fitted spark plug or securely earthed/grounded. Otherwise there will be no spark on either side. Also with such open exits long and dangerous sparks may fly all over the coil.
#	Never do electric arc welding on the bike without completely disconnecting all parts containing semiconductors (ignition coil, regulator, advance) stator and rotor need not be taken off. The same is true for soldering. Before touching electronics disconnect the soldering iron from mains! Never use copper putty on spark plugs.
#	Electronics are very sensitive to wrong polarity. After work on the system, do check correct polarity of the battery and the regulator. Wrong polarity creates short circuits and will destroy the regulator, the ignition coil and the advance unit. As a rule, wiring will always be colour to colour. Instances, where colour jumps between wires are expressly mentioned in our instructions.
#	When you handle the new rotor, take care not to damage its magnets. Refrain from direct blows to the circumference of the rotor. When transporting never put the rotor over the stator. Observe our information relative to transport of the material.
#	Do not use spark plug sockets with a resistance of more than 5kOhm. Better use 1 or 2kOhm ones. Bear in mind that spark plug sockets do age and thereby increase their internal resistance. Should an engine start up only when cold, a defective spark plug socket and/or spark plug is very probably the cause. In case of problems check high tension cables too. Never use carbon fibre HT-cables, never use so called "hot wires" which promise to increase spark.
#	It is a good idea to cover the rotor in a thin layer of oil to reduce the risk of corrosion.
#	Never use a claw puller or a hammer to disengage the rotor. Its magnets might become loose in the event. We offer a special puller for disengaging the new rotor again (see assembly instruction)!
#	Should the motorcycle not be in use for some longer period, please disconnect the battery (so existing) to prevent current bleeding through the diodes of the regulator. Though, even a disconnected battery will empty itself after a while.
#	Please do observe these remarks, but at the same time, don't be afraid of the installation process. Remember, that before you, thousands of other customers have successfully installed the system. *Enjoy driving your bike with its new electric heart!*
