Powerdynamo, assembly instruction for MZ ES/TS 125-150

IMPORTANT:	Please read these instructions fully before starting work on your bike or any modification on the supplied system. Also, please note the remarks on the information page for this system.
	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.
	Before you order a system, please check against the section "you should have received those parts" whether all parts wanted are in the kit. You might want to order a puller tool, light bulbs, fuse, horn, flasher unit etc. Never use anything other than a puller tool M27x1.25 to pull the new rotor again. In case of damage to the rotor as a result of use of other (unsuitable) tools and facilities, the warranty claim expires!
	If you have access to the Internet, see those instructions online. You get larger and better pictures by clicking onto them and possibly updated information. System list at http://www.powerdynamo.biz
Check packing and rotor!	The rotor is sensible to blows during transport. We therefore double pack the material (box inside box). Should the system have been despatched to you via a reseller and arrive not packed like this, please inform us.
Check packing and rotor!	Before assembly, please always check the magnets (try to push them aside with your fingers). After impact the glued in magnets might have broken loose, sticking to the rotor however by magnetic force, so that one does not notice right away. During run there would be considerable damage as a result. Before putting the rotor to the engine, please make sure that its magnets have not collected metal objects such as small screws, nuts and washers. That equally would lead to severe damage.

ES 125/150	TS 125/150
	You will need the following tools for assembly: Phillips Screwdriver, Tip # 1 Phillips Screwdriver, Tip # 2 Hex key 4mm Hex key 5mm Spanner 8 crank ring- or socket spanner 11
	To disengage your old rotor, you will need a puller screw M10x90 (part no. 89 99 026).
	To disengage your new rotor again, you will need a puller M27x1,25 (part no 99 99 799 00). Note: never use a claw puller, a hammer or any other device, that will shake the magnets off.

Notes on wiring: Experience shows that in the course of time nearly every motorcycle experiences changes to it's wiring. As a result, wire colours and wires themselves on your bike might differ to those we describe. In case of doubt, please consult the original wiring diagrams for MZ on the homepage of MZ-B.

	You should have received those parts! Please observe 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).

Make sure your MZ rests securely on her stand, preferably on an elevated work bench and that you have good access to the generator side of the engine. Disconnect your battery and take it out of the motorcycle. For driving without battery, please observe our information on driving without battery. 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.
relay method (supplied as standard) advantage: This option will allow you to use your ignition switch as before. Nothing changes disadvantage: You cannot ride without a working battery. (Unless, in an emergency you pull the brown wire bringing earth to the relay so that it has no longer contact to earth.)
position 5 method advantage: This option will allow you to ride your bike without an battery. A plus for vintage bikes driven only rarely. disadvantage: To switch off your engine you will have to switch your ignition lock briefly to position 5 (formerly pushstart/emergency position). Your engine will not stop when you normally switch off and it will start, even without inserting the ignition key, as soon as it is kickstarted. Sure you may put a secret extra switch.
kill switch method advantage: You may drive without battery, a plus for historic bikes driven only occationally. Disadvantage: You have to buy the switch and you need to install it on the handlebar. We offer such a switch. Tip: You may re-function the flashlight switch to do the job.

	Note: When you make use of the non-battery options and have side indicators (flashers) at the same time, you will need to install a high capacity condenser (22.000µF) in place of the battery to smoothen the pulsing voltage. Otherwise your flasher unit will go heywire.

	Disconnect all cables running from your old generator to the regulator and the ignition coil and remove them. That is: the DF wire (normally green/blue) the D+ wire (normally green/red) the ignition coil wire (normally green) the ground wire (normally brown) Remove the dynamo, the regulator and the ignition coil.

	Should the arresting pin on the top right corner of the generator seat still be in place, please take it off (pull oder cut it). It will otherwise present the new system from beeing installed. There is no harm in that, as the pin had only the task of preventing wrong setting of the old generator.

	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 baseplate as seen here. There are 2 sets of them, one used for MZ. Please observe that the stator wire has to pass the opening marked "wire" in the picture here. If you pass it the other opening, timing will be wrong and the engine will not run.

	Put the base plate (consisting of the outer steel ring and the inner aluminium plate) with the stator hanging loosely from the unit into the place of your old generator. The larger black coil will have to show into about 5 o'clock. Make sure to use the correct set of fastening holes and screw the plate down with the help of the 2 countersunk screws M5.

	The photos show how the outer steel ring has to be positioned on the old generator. 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. (The photo shows a similar engine!)

	The steel adapter of the system will come to sit at the upper recess for the dynamo, as shown here in the picture (and not somewhere further down the engine as you might initially tend to think). (The photo shows a similar engine!)

Put the stator coil back onto the plate, take care not the damage the wires. the stator has to snap in rather sharply. If it sets soft, you have probably squeezed a wire underneath! 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 touch the rotor, damaging it. Screw the coil down with the 3 screws M4 and tighten.

	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. Check further, that the rotor runs freely above the base plate. Tighten the rotor with the screw M7x40, not forgetting the supplied washer. To undo the rotor use a puller M27x1,25.

Mount the regulator/rectifier unit, the relay and the electronic ignition coil at a convenient place (say next to the battery). You will find different solutions for ES and TS models.

	You may use the bottom part of your old regulator to make a holder for the new. For Instructions click here.


The following steps will depend on switch-off method chosen
In all cases, you will have to open the headlamp housing and identify pin 61 at the main switch.

relay and kill switch option
Disconnect the 2 blue wires from pin 61 of your ignition lock. Do not cut the connection between the 2 wires (in case they had been sitting on individual terminal pins, connect them now using a piggy back terminal). Insulate the wire terminals, so that they cannot accidentially connect to ground or other terminals. Pin 61 will remain empty.
position 5 option
Disconnect the one blue wire from pin 61 of your ignition lock that runs to the charge control light. This light will not function anyway without battery and only in that case you have to resort to things as position 5 method. If the 2 blue wires at pin 61 are connected in one terminal, you have to cut this wire. The other blue wire running down to the regulator will be used further on. It has to remain connected to pin 61 of the switch.
	After you have taken the old regulator off, you have the following wires to deal with several brown ground wires which will be connected again to ground with the new regulator a blue wire 61 which will be connected to the red/green single wire at the new regulator a green/red wire D+ and a green/blue wire DF which will be eleminated right down to the seat of the dynamo. a red/green wire 51 to the fuse will be elininated

Please note: All our 6 Volt systems do not support the charge control function!

Connect the parts as shown in wiring diagram 71ir6:

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 two wires (red and white).

Put the provided 2-position plug housing onto this plug and insert the two wires (red and white) from the generator. Make sure that the terminals engage securely in the housing and that you connect:

white to white
red to red

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.

The brown wire from the new generator with the round eye terminal have to be screwed to the holder frame of the ignition coil (ground). This connection is very important. Please don't depend on the frame as the earth-connection. Varnish, oil and dirt prevent often a good contact!

The regulator/rectifier has a compact plug with 6 positions, of which two are not used. From November 2007 onwards 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 a white 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 ...

... 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 10A-fuse between battery and vehicle circuitry.

The 6 Volt regulator has NO provision for a charge control light!

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.

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.

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.
#	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 electronics.
#	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!*
