Re: 12V Voltage on Robot Frame (Perhaps because of a BaneBot)

This is how we fix case short issues with the RS775:

These motors have cost us failed inspections in the past. Usually the windings short to the armature which grounds to the frame through the bushings at either end or the interface with the output shaft. Your only solution is to get a new one and hope it isn't case shorted or mount them in a plastic to electrically isolate them.
