I have a big problem I replaced my starter and my selonoid 3 times an i have the new starter on for a week and it is stuck on and I can take the key out and it won't shut off it finally killed the car so we towed it home and put a new ignition switch on and we were going to test it so we hooked up the battery and the starter was ticking and I didn't have the key in the ignition so I have replaced the selenoid the starter and the ignition switch so what else could it possibly be please help

 

with the key in the off position check for current on the wire that engauges the selonoid from the ignition switch= should not have current on it, with a test light lnowing how the circuit works you should be able to narrow down where current shouldn't be with the key in the off position and that'll tell you where the prob is

 

if it does have a current how do you get rid of it
