1986 ford f150 standard cab, manual trans with 3 plus overdrive.
1989 302 rebuild v8. When trying to start ocasionally the ignition continues to turn over
Even after the engine fires, the starter continues to turn over until I have to disconnect the battery to stop it. Then it fires up fine afterwards what could the problem be. I'm thinking the starter, or the ignition switch but I also heard it could be the starter cylinoid.
While it's stuck turning over, disconnect the wire from the 'S' post of the starter solenoid. If it keeps turning over, either the solenoid is bad, or the starter is drawing too much current and welding the solenoid shut. If it stops turning over, then the problem is upstream - either in the ignition switch or the wiring in between.
If you pull the small red/blue wire off the solenoid and it keeps turning, then yes you probably have a bad solenoid. If the solenoid is new, suspect it even more, the new ones seem to have this problem.
