Marcus grabbed his multimeter. He measured the resistance across the motor leads and megged the phases to ground. Everything read perfectly balanced—the motor was healthy. He then turned his attention to the auxiliary contactor responsible for the speed transition. There it was: a tiny plastic fragment from a worn-out housing had jammed the relay, preventing it from snapping into high-speed mode.
