Trouble killing spark

[bama]

I have another Jonsered 625(my cheapie/beater) that I am working on. I hope to have it running for less than $50 total investment.

I can't seem to kill the spark. My switch works and I have ground on the coil to the kill wire, but it won't stop sparking.

It is the 2 piece ignition system.

What could be causing my grief? I have tried two other switches with the same result.

Anyone???

Bueller?......Bueller?.....

your switch goes to the trigger module.you also need the module wired to the coil.

The primary coil has the kill wire that plugs into the switch. Am I missing a wire? I don't know what you mean by "trigger module". Is that the secondary module?

looking at the flywheel the trigger module is on the left side, right side is coil. should have 2 wires coming out of the module.

I had them backwards. I do have the wire from the trigger module going to the switch. If I can get a ground from the switch to the crankcase and from the trigger kill wire to the crankcase, it should kill the spark, shouldn't it?

sounds like your switch is correct, there should be a wire from the module to the coil, it's routed in the grove below the flywheel, then meets a short wire from the coil and screwed together. fastening your switch to the case will ground it.

That is exactly how it is setup. I do have the switch installed and it grounds to the crankcase when the switch is turned off. That is what has me so baffled.

unplug the switch and take a jumper wire and plug into wire from the trigger module, ground against the engine. switch may be bad.

Good idea. I hadn't tried that. I will do it when I get home.

I tried grounding the kill wire directly to the crankcase. No joy. I still can't get it to stop sparking.

 

[sugarbush]

try a ground wire from the coil/trigger module wire to ground.

Do you mean attach a wire from the the coil to the trigger module ground wire?
