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?
