After recording this video I checked the motor bolts and they are tight. I didn't see any problems with the hall sensor wires. The black battery wire had bare wire exposed, but was not touching against anything conductive.
The problem was resolved when I replaced the motherboard. It wasn't hard to replace. I ordered parts from eWheels.
