Hello all,
I have a 1968 f100 that is driving me crazy. Issue: Went to crank it and just got the old "slow speed turn from the motor", as if not enough juice to kick it over. Tried jumping it off but no luck, however, after I turn key off, starter kept stayed engaged and kept trying to start. How is this possible if key in off position? Solenoid? Switch? Wiring? I replaced solenoid, still no luck. Tried new switch, still no luck. traced wiring as much as I could but didn't see anything wrong. Would a starter cause this? If so, please explain. I do not understand how a starter gets power and stays engaged if key is off.
