David, those coils have an extra ground wire that is part of the “kill switch” setup on that motor. When the throttle lever is moved to stop, the lever contacts both coil ground wires that sit in a tiny housing built into the magplate. The wires and eyelets are alternated with insulating bakelite washers within the housing so they don’t contact each other. It sounds as though the kill switch wires may be broken off.
