Powerdynamo, assembly instruction for BMW/EMW R35

IMPORTANT:	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 gasous pollutants and noise. In most cases emission of pullutants 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 countgries, please check locally against your road licencing 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.
	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. 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 carefull during the first testruns. 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.
	Our systems are NOT tested for use with other third party electronic devices and may cause damage to such parts. Possibly existing electronic tachometers will not work with the new system. Read our information for suitable solutions.
	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 with non encasted magnets try to push them 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 result 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.

	You should have received those parts: trigger cam with disc sensor with holderbase ignition coil and hightension cable electronic advance unit voltage converter housing (cover), 2 parts

Make sure your R35 rests securely on her centre stand, preferably on an elevated work bench and that you have good access to the front of the engine. You will have to turn the front wheel from side to side for good access. Disconnect your battery and take it out of the motorcycle for the time of work.Drain the petrol (gas) from the tank into a canister. Take care not to spill any petrol and refrain from smoking. Disconnect the tube running between the tanks sides under the frame tube. Take the petrol tank off the bike and put it to a secure place for the time of work at the bike.

	Take the complete concatc breaker unit, including its housing off. There will be new parts at this sport. If you make yourself a small holder for the bowden cable, it may remain for optical reasons. Technically it will be defunct.

	Clean the drilling hole in the cam shaft. There has to be placed the pin of the trigger unit. The pin is a little carved-in (for better hold), but you should better stick it in. The pin has a even plane for escape of air. Before you stick-in the pin, ckeck the correct position of the pin against the sensor (same level).

	Place the preassembled sensor unit on the motor case. Mount it with the both threaded rods M4. The new housing will be later mounted with that rods too. Adjust the rods in that way, that the housing can be good mounted later (and the rods don't come through).

	The new rotor disc should be in line (or about so, 1 or 2mm to the side will not matter) with the metal core of the pick-up. The gap between the pick-up core and the surface of the elevated section (nose) of the rotor disc (any of the 2) has to be 0,4-0,5mm. You adjust that by loosening the pick-up screws a little and shift the part. Do not forget the carefully tighten the 2 screws after that. Under vibrations it might shake loose and get destroyed by the rotor's noses.

	Lastly timing has to be set. For this, take the spark plug out and set the crank to top dead center (TDC, marked "OT"), that is the highest position the piston can get. Hold the rotorcam with a flat spanner size 13 and open the upper nut. Now you can turn the disc.

The ignition effected after the trigger has passed the sensor (the system has to calculate the speed and needs the time of passaging). Don't be dazed by this (imaginary) paradox ignition adjustment.
	Turn the crank shaft to the TDC position. Then turn the disc in that way, that the carved marking aligns to the sensor. Refasten the screw (don't forget the lockwasher). If requiered, you can modify the attitude. If you position the disc a little clockwise, you get more advanced ignition, or counter-clockwise, less advanced ignition. But pay attention: wrong settings will damage your engine!

	With that, work on the engine is finished. Remains to find a place for the external parts and fasten them conveniently. We know that this is easy to say and difficult to do, if you want to keep them as much out of sight as possible.

	The following photos show an example of the assembly. They are from the German page www.motorradfreude.de. Here the new ignition coil has been fixed at the front of the frame.

The advance unit and the converter have been placed into a small box which was than fixed between seat and mudguard.


Have a look at the advance unit (the black box). You will notice on the side the wires come out 2 small blue switches. They are used to activate the different advance curves inside the bow.
	Switch 1 has to be at "ON" position whereas switch 2 was to face the figure 2 there (that is the "OFF" position). If not, the system will not function correctly.

	Finally, place the new cover on. It will be held in place by the 2 M4 rods ending in M4 nuts.

Connect the parts as shown in wiring diagram 599.2:
Start with the converter:
	There are 3 wire bundles at the black converter box. (You may tell the converter from the advance unit which is housed in an identical box by those 3 bundles. The advance unit has only 2.): one bundle containing a red and a white wire with open ends a second bundle with a 4-position male plug (only 3 used) containing a red, a white, a blue/white and a green/red wire a third bundle with a 4-position female plug (only 3 used) containing a green/red, a white and a blue/white wire
The bundle with the open-end-wires:	Connect the white (earth) wire to the negative (minus) pole of the battery and the red wire (via a *5-Ampere-fuse*) to the main switch at a terminal there that carries voltage when the switch is ON.
The bundle with the 4-position male plug ...	... connect to the fitting counterpart plug at the ignition coil. Make sure that red goes to red, white to white and blue/white to yellow.
The bundle with the 4-position female plug ...	... connect to the fitting counterpart plug of the advance unit. Make sure that blue/white goes to blue/white, white to white and red/green to red/white. The green/red wire remains unconnected.
Remains the 2. bundle at the advance unit (with the wires yellow, white, red/white):	... get connected to the yellow and the white (ground) wire from the sensor. To connect use the supplied plug housing and plugs. Make sure that yellow goes to yellow and white to white. The red/white wire remains unconnected.
This bundle with the 4- position female plug ...
Finally - and before installing the battery and before the first kickstart - please re-check carefully all connections and fitments against the wiring diagram. Please don't depend on the frame as the earth-connection. Varnish, oil and dirt prevent often a good contact! The system will work with both 6 or 12 Volts (adapts automatically). It will however not work without battery! 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 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.
#	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.
#	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 is to apply changes to customize the firing point before running the system. 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 carburettor, 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 carburettor will have to be re-adjusted to lower settings. Should the system not start after assembly, first disconnect the blue 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.
#	The spark of classic, points based ignition systems has with about 10,000 Volts with little energy and looks therefore yellow and fat (hence it's visible). The spark from our system is a high energy spark with up to 40,000 Volts and therefore very sharp (needle thin focused) in form, and blue in colour, which makes it not so visible. Furthermore you get spark only at kickstart operated speedss and not by pushing the kicklever down slowly with your hand (as you might get with battery based ignitions).
#	Systems using a twin outlet ignition coils have a few percularities. 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.
#	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.
#	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 differs between wires it is 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", never use resistor spark plugs.
#	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 screw 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!*
