Help with some ignition problems

[kevinv]

Hello,

I've had a couple of ignition related problems in the last couple of weeks. One day I turned off the ignition and the engine kept running. I pulled the I post wire on the solenoid and that cut the engine. I think I had another case of getting I post power with the ignition key off. Does this sounds like an ignition switch problem?

Yesterday I went to start it, released the key and the starter kept running. I turned the key to the off position, starter was still running. I removed the S an I post wires on the solenoid, still the starter was running. The last thing I did was just wiggle the solenoid some and the starter stopped. I think since the S post wire was removed but the starter still ran, this would mean the solenoid is bad rather than the ignition switch.

The above problems might indicate a bad solenoid and a bad ignition switch. Both are fairly new. The solenoid, just a couple of months. The ignition switch, last year. The duraspark module is also just a few months old.

Any help with what might be going on would be appreciated.

Thanks,
Kevin

From what you've described, it's definitely the solenoid. The I terminal gets power from the solenoid, but supposed to be only when the solenoid is energized. Then there was your experience yesterday. Definitely solenoid.

Not uncommon for early failures in solenoids these days. As with most anything else...

After you replace the selenoid keep an eye on it. A bad ignition switch can cause a good selinoid to go bad.

Sounds like both need to be replaced. If the switch doesn't stop delivering power to the coil it won't shut down your engine. It should be a single wire (resistor+green/red?) that goes from the switch to the coil.

Good luck! Electrical gremlins can be a real pain.
