Re: Could a magnetic field around CIMs cause fuses to blow?

Using the ohm checking capability of a multimeter, check for continuity where there shouldn't be continuity (i.e. motor wires on opposite sides of the drivetrain)
Backfeed was prevented, we tested the robot while it was off the ground so the left motors were not spinning at all and the fuses to their Victors were removed leaving only one possible power source... we think.
