Re: starter keeps running after car is running
Only 3 things would do that.1)"S" wire is touching the solenoid positive lead,2)ignition switch is bad,3)the solenoid contacts are stuck.
If you reverse the small leads on the solenoid it wont do anything & it wont hurt anything.
First thing to do is see if you have constant power on the "S" terminal with key off.
