DC Motor Help Needed

Trying to diagnose why the smoke came out of my ExtremeAir 12v compressor motor. I expected the pump to be seized, but it was fine.

It's obvious it's been hot--the wiring is melted. Trying to check the condition of the armature. Is there supposed to be continuity here:


and not here?


Anything special about the wires that run from one brush to its partner--there are 4 total? They are melted and I was going to replace them.

All I've found was that the motor was not well grounded to the van. Will that cause failure?

TIA
Z

So there should NOT be continuity in either place?

Re: DC Motor Help Needed

You have a shorted armature. The only fix is a rewind.

Contact George at Extreme. I put his contact info below. I don't think he'd mind, he seems intent on having satisfied users of his product. He was very helpful when I rebuilt mine.

Re: DC Motor Help Needed

Car headlights are actually devices that suck in darkness,convert it into smoke and store in in various expensive electrical devices. When it leaks out the device dies.
