So if the engine ran at all, even wired incorrectly, or with 12v to that black wire all the time, the pick-up coil is likely OK ?

If it ran, I wouldn't suspect the pick-up coil unless it changed... such as a smoldering lump on the end of the wires.

the pick-up coil should be pretty simple, just a coil that you pass a magnet by to induce some current.

That being said, some IC's are polarity sensitive. drive them the wrong way they stop working.

what baffles me is when it seemed to be wired the wrong way, it only fired with the starter running , but perfectly with the "wrong" wiring. I must be missing something really obvious.

It looks, from the diagram, that the solid black, should be connected to the triggered side of the starter solenoid (only gets power when cranking). The black/white is ground.

The orange/white(or yellow) should get power when the switch is in the on position. Goes to coil and igniter.
The black/yellow is the wire the igniter uses to trigger the coil.

Orange and green are from the pickup.

Looks like the igniter is turned on by power being applied to the orange/white(or yellow it's hard to tell).

Black is trip for starting to retard timing and is only powered when starter motor is running.

It should be fairly easy to bypass everything in the bike's wiring harness if necessary or construct a simple one to make it run.

Sounds like runs only when starting is indicating no power at the orange/white(or yellow) when key is on. Power would feed through the black lead until the starter motor was disengaged.

Serow, some electronics are polarity sensitive. Wiring the pickup one way will result in + going into one of the leads and - going into the other. If the connections were reversed, the one that should be + would be getting - and might cause something in the pickup sensing circuit to die. Just depends on whether or not they polarity protected it.

OK...I'll shut up now. Hope I didn't confuse matters for the OP.

Keith,
I think Steve has figured this out. Check the diagram of the pins on the igniter in the link here - same one I sent previously - and make sure you have 12V at pin #5 when whatever you are using as an ignition switch is turned on.

I have used a connector strip to avoid muddles. Perhaps finish tomorrow, if it won't spark then, it's time to hire a real electrician. Thanks for the help.
