Pm Generator Speed Sensor

The PM generator is a permanent magnet generator mounted in the transmission and is used to provide vehicle speed data. It is designed to be used with quartz and digital speedometers and will replace the current transmission speedometer drive gear and sleeve.

The purpose of the PM generator is to provide a speed signal that is proportional to vehicle speed. This signal is transmitted directly to the speedometer circuitry in the vehicle.
