Re: Banebots RS-775 Case Short

A picture of what I suspect is the problem with the motor I disassembled.

Notice the "dents" in the green insulating paint at the corner of the armature core, where the wire wraps around it. There are two places where the metal is showing through. The wire is insulated with a thin coat of some type of paint also (in the old days, it was varnish, I don't know what these ones use). It doesn't take much to scrape the insulation off the wire, and have it short.
