    1986 yamaha xt600 tenere

    I have a friends 1986 yamaha xt600 tenere that someone had hacked all the loom out completely, I have wired everything up now apart from connecting the CDI unit to the engines source and trigger coils, I was trying to avoid removing the engine cover but could someone make sense of the different coloured wires? On the engine side they do not match any wireing diagram

    Could someone ID the wires from the engine side?

    This CDI unit has 10 wires FFS

    No, not really, but one could assume that the pain of similar wires are the charge coil and if you put a meter over them and kicked you would get a reasonable voltage depending how quick your meter works, I'm going to wildly guess 30V.

    I cant say with the others but it gives you less options

    I already have the charging system connected, 4 of those 5 wires in the photo are for the CDI I did think of using the meter but I have found with source coils if you switch the wires the engine will run but not well and if the source coil gets wired to the CDI trigger it will all be over

    So yeah the ac charging are the 3 same wires to the rectifier, but the coil to energize the ignition are often different as from that picture.

    You cant really test a cdi without a dedicated jig, best plug it into another running bike if you could find one.

    Yeh he has a CDI tester jig, I had to take the side cover off in the end to find the wires to the trigger and source coils and found everything was well fucked inside on the charging coils side and I found 2 big dead beetles. I am taking the stator to that DC armature guy and he sed around $300 + GST to repair it

    I got the repaired stator from DC armature, he had to redo all the charging coils, but I still have the same problem with the different colored wires this stator has for the trigger and source coils,

    The trigger just sends an electrical charge. Chuck a meter on it and you'll soon know which is the positive and negative sides.

    The coils cant provide anything other than a AC wave. The trigger pulse is rectified on input to cdi and the rapidly rising positive voltage is seen as a trigger voltage on the gate of an scr or just a logic level 1 on a later digitized ignition.
