1980 f150 starter continues to run after truck cran ks up
Could be the starter relay is sticking or the ignition switch is still sending the power to the starter relay while in the run position. Pull off the small wire on the relay and test for voltage in the run position if none is found then try the crank position, voltage should be present then go away when key is released back to run, if it does this then replace the starter relay and make sure that the ground surface is clean and the mount screws are tight and not pulled through the metal.
It could also be that the bendix is keeping the gear extended when it should be retracting. It could be that the starter isn't aligned with the flywheel. So, it could be an electrical or mechanical problem. -- Does it happen every time?
My guess is a sticking bendix maybe Caused by a broken bendix spring.
Where's the bendex spring located ... My ignition was stiff when starting . Then started should not stop had to disconnect battery to stop it
Toni, the bendix spring is inside the starter, it is part of the drive. Sounds more like you have an ignition switch going bad,
