Question single wire starter doesnt disengage

im an a.s.e certified technician but ive got a new one here. im working on a 1988 ford f250 air force truck. it has the 351 windsor in it and a single pole starter with the typical fender mounted solenoid. when properly wired the starter wont stop cycling until the battery is disconected. the solenoid and wires are brand new. i believe the contacts activated by the pole shoe are damaged. any help is greatly appreciated

We've had some do that when the battery was a little low or the drive was sticking on the shaft.

If you remove the starter and spray WD40 on the shaft, it may start okay. You don't have to remove it completely to gpray the shaft.

Re: single wire starter doesnt disengage

Have you tried it with a jumper battery? How abouth all of the grounds and connections. When it's hanging up, if you tap the solenoid does it quit cranking?

I forgot to ask if you unhooked the wire on the solenoid from the ignition switch to see if it stops. It could be the ignition switch.

Re: single wire starter doesnt disengage

Hi, a sticking solenoid, a sticking bendix, or a chewed up flywheel ring gear can do it. Also an in-correct flywheel, bendix, or a miss aligned bell housing. [dowel pins left out]
