Only One Coil Sparking

[tom203]

?...since one side is sparking, the case ground is unlikely to be the main issue?

I agree ...this is a simple two wire signal generator.
You can just hook up the ignition stuff, lights etc aren?t needed for starting.

Fore checking voltage drops you can do with just the Orange/White stripe wires circuit fuse (O/W wire in diagram)
To START the bike,(O/W) will also allow starting the bike via the button ,the kill switch and the solenoid, and of course, you also need the the master 30Amp on the red wire, but lighting (Orange/red stripe) (O/R) or Orange/Green stripe (O/G) fuse aren't needed.

The headlight especially will drain your battery quickly, but the coils also draw quite a bit of current....I have an old car battery I use if I am fiddling awhile too long but if you think it through first and tkeep an eye on your motorcycle battery voltage while you troubleshoot, it'll be ok. Just don't drain it below half for very long. They degrade quickly without a recharge.

You can check the coils themselves by disconnecting them from the circuitry and applying a very short duration 12 volts to primary coil. They spark when you DISCONNECT. Don't do this around fuel vapors.

thick cloth washer? well, starining myself, but perhaps the igniter case didn't sit flat on the plate, but a steel washer would do too, so no. It's a mild entertainment trying to understand a PO's thinking.. ("previous owner")

Still, even the cloth washer needn't be "in the way" of a good ground if the bolt itself lands on shiny metal and is threaded into a tapped lug on the frame...

since one side is sparking, the case ground is unlikely to be the main issue.

Agreed, but still,....WTF?

Howsit Everyone,

I managed to get a secondhand CDI/Signal Generator and it fixed my problem.
Thank you everyone for your input. Really appreciate it. Now it is taping the whole wiring loom again, put everything back and go for a cruise

Sounds like a happy ending!

If you're severely lacking in entertainment some dark and stormy night, and if the ignitor is one with a metal case, you can usually figure out a way to open it and inspect the circuit board. Odds are good that you'll be able to see the component that let out the magic smoke. Usually a MOSFET, if I'm identifying the largeish squarish black widgets with three legs and heat sinks correctly.

And yeah, if you're looking for one on fleaBay, for some damfool reason almost everyone calls it a "CDI" even though actual CDI ignitions were relatively rare. I have absolutely no idea why everyone picked up on that term.

Henceforth, you shall go by the name of, "One Coil Sparking."

Haha - I humbly accept it my friend. My next tattoo and sewn on to my patch... When i join a bike club that is...
