Hi all,
I checked our 3 motors last night and found 2 of them to be shorted, if you call 6 ohms shorted.
I set up a smaller battery, and a 40A breaker and proceeded to 'zap' them by putting one wire on the terminal and one on the housing.
One motor showed no sign of a spark and was healed and works fine now, and the other one showed a bigger spark on the first touch, but no sparks on subsequent tries, unfortunately, it was only semi healed in that it continues to have 300-500 ohms of case to terminal resistance.

While I'm happy to get one motor working, I have to say that this is the craziest fix, and I'm not happy with having to have done it.

If you try it, please be safe.

Mike
