I replaced my starter and when I tried to start it kept trying after key was off. It is a 19995 Oldsmobile Cutlass Ciera SL.
Starter Stuck On
This is common when the terminal ends get tightened up and touch. If this is not the case you can remove the smaller wire from terminal “S” and test for constant voltage with the key “OFF”. If there is voltage found, trace back through the selector switch and finally the ignition switch. No voltage found, make certain the big wire isn’t near or touching the small wire, reattach and test again. If the issue reoccurs you may need to replace the starter as the replacement is shorted internally(not common at all). Since you made need a wiring diagram to understand the circuit I have provided one.
