Vette Continues Running With Key Off

Fixing problems caused by Bubba on restoration. Car starts just fine but when key is turned off it continues to run. I can unhook wire from coil marked on coil at Bat+ and it shuts off. I have checked schematics provided by member on this forum and feel I have missed something at key switch connector. Any ideas? Thanks.

Try this, start it, turn it off and then unhook the alternator 2 wire plug and see if it dies. I've seen the 2 wires in the alternator plug reversed and cause this.

Have you checked the adjustment of the ignition switch on the lower column? Also can you turn it all the way to accessories?

When this happened to me it was in the starter solenoid...

I had a heck of a time finding it. I had an intermittent short inside the solenoid wiring and I'd had this electrical draw for ages that I could not locate. Then, suddenly last year, the car would not turn off with the key. I trouble shot the ignition switch, and when the car kept running even I unplugged it, I figured the flaw was elsewhere. By this time I was thinking that this was related to my previously identified amperage draw with the car off. SO, I hooked up my ammeter and started wiggling the wires all over the place......once I got in the starter area it became obvious that something was going on there. I replaced the starter and the solenoid (lifetime warranty) and it's all good.

Do you have the original ignition system? Only ask because with an MSD ignition you have to put in a diode to break the current.

Found issue. Bubba installed toggle switch between ignition and coil. When I cut out all of his splices when redoing wiring I did not tie coil back into ignition system so coil had 12 volts continuously.
