Hopefully it's something simple like a wire that came loose or a wheel or gear that is binding on the body or frame.

Agree, it could be either. I'd put an ammeter in the circuit to see what happens. If it's electrical, the amps would drop to zero, if it's mechanical, the amps would jump up and the volts would probably drop because of he drain. That should give you an indication of what's going on.
