Starter won't stop..........

[D Taylor]

I'm close to resolving my electrical woes;

after replacing cables and regulator, etc., I finally had the starter tested and installed a aftermarket Lucas starter on my '72 deisel.

Started and ran better than ever twice.........3rd, 4th and 5th starts, the starter won't shut down...evan after disconnecting all wires from the ignition switch; the only thing that works is pully the battery cable.

put the cable back, nothing until I turn the key again.....and then it won't stop again.

The new stater has a stud on the starter casing that wasn't there on the original, is this an additional ground?

As always, any suggestions greatly appreciated.

Take the starter back where it came from! Have them replace it!

The key switch on my 4000 and 4500 both seem to stick in the start position after the engine is running rather than springing back to the "on" position like they are supposed to do. Once I noticed the starter on my 4500 smoking before I realized I needed to move the key back to "on".
It is an aftermarket Lucas and has that additional stud on the case. I assumed it was an extra ground.

Pull the signal wire from the solenoid when it acts up and see if that stops it... or pull the range lever in gear and see if that stops it. Either way, if it stops, that would suggest a bad key switch... or at least you would check the switch and wiring.
If it doesn't stop when you remove the signal wire, that suggests that the contacts in the starter are burnt. I'd take the starter back, or at least call the seller and raise hell about it. They likely have a policy about no returns on electrical parts.... so your mileage may vary on that one.

If they won't do anything about it I'd probably take the end cap off the solenoid and see if I could clean the contacts or see what's going on...

The lug on the case is for the ground cable.However i've seen these lugs work loose and you will lose the ground connection.So i always install the ground cable to one of the starter mounting bolts.I would check that wiring harness.It may hove gotten hot and have two wires touching inside.
