ignition switch engages starter after engine is running???

[davecobra]

Well I tried the jiggle test , if I jiggle the key it will cause the starter to engage, if I jiggle the wires nothing happens, everything is tight, it points to the switch, I guess it could be cheap switch 29.00 napa switch, x two. I am almost ready to put a seperate pushbutton switch before it tears something up. this is not my first car to build, I have several under my belt, everything from a sterling kit car to a blown and stroked 34 ply hemi coupe, my current driver. I understand how wiring works and this may be just a bad switch twice in a row, but sure seems strange. I do not have a gear reduction starter, just stock.

That's a bad switch. I can't envision how it could be anything else. BUT, if you want to be absolutely sure, remove the solenoid wire from the back of the ignition switch and put a 12v test light on that ignition switch pole instead. Then repeat your jiggle test. If you can get the light to come on by jiggling the key then you absolutely, positively have a bad switch and you've eliminated the possibility of some cosmic back feed through the solenoid wire (which I can't think of how that could happen anyway).

I recently had a big thread about screwing around with my starter and damaging teeth on the flywheel.

I'll tell you what, the next time I even get a hunch I got starter problems I'm gonna STOP right there and get a handle on it. PITA changing out a ring gear.

...the new one works beautifully by the way.
