I had the starter go out on my 89 Cherokee. I had it rebuilt, but now there is another problem. When you start the car now, the starter still continues to turn. Not only does it sound aweful, it will burn the starter up before too long. The Cherokee was my daily driver for over a year and it never did this before. Any of you guys had a similar problem? I really need to get this fixed to I can start building this one.

Thanks

The over ride clutch in the starter is bad or the starter drive gear does not have enough clearance at the sun gear flywheel ring/sun gear. The latter would cause a very shrill screech after the engine starts.

It just sounds like the starter is continuing to turn over after the Jeep has started.

You have to figure out wether itīs electrical or mechanical. Most probably mechanical. The drive gears in the starter, donīt want to disengauge from the flywheel/flexplate gears. Makes a pretty good racket when this happens.
Some mechanical causes, could be the spring in the solenoid sticking, the solenoid plunger rusty and binding, the gear sticking on the shaft or the bendix sticking. Mechanical/electrical combination could be the contacts in the solenoid sticking (they sometimes spot weld themselves when the non-ferrous coating wears off). Or the contacts in the starter relay sticking.
Iīd bench test it and see if the gear/bendix stays/hangs in the engauged position. Check the fork pin, the pin the fork pivots on, so the solenoid can pull the fork rearwords to push the gear forwards (gear end of the starter being front).
Havenīt seen it on a Mitsubishi (jeep) starter, but on many GM starters thee is a thrust washer between the gear and the bearing end, so the gear doesnīt go in to far.
If itīs electrical it can heat up your starter pretty quick, if itīs mechanical it can heat up your over running clutch.
If you test it with a pair of jumper cables, make sure itīs tied (held) down pretty good, it jumps when engauging. Put the nuts onto the electrical connections before, putting power to it, the juice will mess up the threads pretty fast.
