I just had one do the same thing, metered the plug end and had a dead short (0hms resistance).
Pulled apart the plug end and all was fine, always worth a look in there. Pulled motor cover and found two of the relay connectors touching. Spread them apart, fed some slack into the inside of the rigger and all is well.
I seem to remember a rigger getting turned 360 on the swivel, guessing that pulled the wire and caused my problem.
