DevilDog6154 yea seems everyone i call to work on these trucks or get advice from them they laugh at me and tell me they dont work on them much anymore and the parts are hard to find.

8gitmusik1 Using a reputable local rebuilder for your starter or alternator will give you the best quality, and is probably your best option but these shops are getting harder to find, as the few old, established and good guys that have the experience at least, in my area, have retired, or passed. Or new, from Oreillys or Napa, AZone, even if the parts are from asia, they can last a good while. Good luck with your fix.

Hey DD6154

Check out DB ELECTRICAL

Its a Nippo clone but as aGR starter its a decent design and better starting than stock.

NOTE:
They also have ALTERNATORS for your vehicle and may have the 3G higher capacity (if your looking to do the conversion and go serpentine belt )

They also have v-belt alternators that would go on your 1990 if your seeking now. They can be had at a good price and they have a fair return 1-year no questions warranty.

I used the GR starter above and have nothing bad to say and they shipped it and I recieved it in 24 hours with no upcharge for receiving it that quickly.

Hope this helps you.

And, just for the record, no I dont work for them or have any interest with them, just used their product.

YMMV

Btw, if ya need glow plug harness or push button glow plug complete new wiring harness and update to stancor/white rodgers contactor conversion, PM me and I'll give ya a great recommendation on doing that.

Good luck DD ... hope things work out.

DevilDog6154 The motor was running when it happen even after the power loss. The only reason the motor shut off was cause my foot come off the clutch pedal. No I haven't check anything it's at a friend's shop so he can do the assessment for the insurance.

The starter would be the type of heavy amperage draw I was thinking of in an earlier post but I don't know if the starter acting up is the cause or just a symptom.

Did the engine actually start when the fire occurred?

Have you inspected the batteries and checked their voltage?

Have you inspected and improved the ground connections yet to both the frame and the starter that were damaged?

Have you attempted to start the truck since this happened? I am not suggesting you attempt to start it, I just wonder if you have tried. I would inspect the starter before attempting to supply power to it again.

I hate to speculate without you first doing a further visual inspection of the starter but my dad reminded me of a starter on an old tractor that failed to disengage many years ago and the engine rpm kept rotating the starter and it burned up. He remembers the starter actually became a generator and produced current. This back amperage then started burning up wiring. (Fortunately there is not much wiring on those... Lol
It was an old WD45 with its original 6v converted to a 12v but the problem was it was a push button type starter. The push button had either corroded or maybe had ice build up and remained pushed in rather than springing back out once the engine turned over.

I guess it would be possible for this to have happened with your starter if the solenoid stayed engaged.
