Traction Speed Sensor
The traction speed sensor is attached to the right side
rear wheel motor (Fig. 21). The sensor provides ground
speed information for two (2) options: the Pro Control
Electronics and the speedometer kit. It uses a magneti-
cally based, Hall Effect integrated circuit. As the piston
group in the wheel motor turns, the sensor accurately

The red connector wire (connector terminal A) is the
positive lead, the black wire (terminal C) is the ground
lead, and the white wire (terminal B) is the signal output.
