Hi all,
I am having issues with an 89 KX500 rebuild i have been working on for a while now. I've just got back into the project after a 8 months of not touching it. Anyway.... I have no spark what so ever. Here is what I've done:
- Replaced stator / pulser coils
- Replaced CDI
- Replaced coil
- New spark plug
- Made sure coil is earthing
I haven't adjusted my timing, the stator plate is bolted up inline with the marking on the casing. For the time being, I'm not concerned about timing, as even if it is slightly out I should still see a spark. Can anyone explain to me abit about how the KX ignition wiring works? What the stator, pulser, CDI and each components relevant wire actually does?
I have the following colour wires on my bike:
Stator & pulser coil plate:
- Black / yellow (Earth I think)
- Black / red
- Red / white
- Green / white
CDI:
- Black
- Black / white
- Black / white
- Red / White
- Green / white
- Yellow / black
Coil:
- Decent earth!
- Black (To black from CDI)
My CDI unit has two black / white wires, one of which is for the kill switch and the other I'm guessing runs to the back / red on the stator? I have tried swapping these round. For such a basic ignition system, it really seems to have stumped me. No wires are shorting and all connectors are good. I have even tried two different flywheels. Does anyone have a wiring diagram or can anyone suggest anything I have missed?
Cheers,
Jim
