    i have a 2000 f250 superduty and i took it off road and ended up blowing the fender mounted selinoid and an alternator. now i replaced them and when i got the truck running the stater stays engaged. i replaced both selenoids, the starter, ignition switch, and the tumbler and it still stays engaged. i have run out of ideas and any help would be apreciated.

    The solenoid may be defective out of the box- it happens.

    Its prety simple to ck the wiring going to the solenoids. There should be no need for guessing at replacing parts. Simple test light and wiring diagram is all u need. Starter circut is a fairly simple thing. What engine does it have? I will try to look at the schematic. Did u wire the solenoid wrong when u replaced it?

    Just a thought

    maybe the starter not still running but the Bendix is not retracting.

    put a test light on the wire between the solenoid and the starter. If the light stays on when the key is released then its a solenoid or wire problem. if the light goes out but the starter is still engaged then its the starter.

    i fixed it. i took the selinoid off and cleaned up the wire connections a little bit and it works fine now.

    A bad connection is not going to produce current to the startor. Did u happen to put the wires on the correct way this time maybe?

    yeah i switched them up too. i had one of my friends put the new one on for me cause i work full time and go to collage so i dont have alot of time to work on it, and he screwed it up he ran the wire that goes to the starter to the wrong terminal and was sending power to the starter all the time.

    Ironically, I'm having the same problem with an 02 V10. Solenoid went out. Haven't had time to replace yet.
