Testing the Rear Wheel Traction Motor (continued)
Electrical System: Testing the Electrical Components
If logic voltage is present at the controller, and CAN bus communication
is suspect, the CAN bus circuit is damaged. The CAN bus wiring
should be checked for corrosion or damage and cleaned or repaired
as necessary. The rear wheel traction motor controller CAN bus
transceiver can also be tested if necessary; refer to
(Nodes) on the CAN bus (page
• If 00.0V is present at the rear wheel traction motor power bus circuit, the
circuit is damaged. The circuit wiring should be checked and repaired as
necessary.
• Rear wheel traction motor speed should be displayed while the traction
motor is engaged TRXN 3 Speed.
6. Unplug the 48V battery disconnect; refer to
5–9).
7. Locate and disconnect the rear wheel traction motor cable electrical
connections at the machine wire harness. Check the motor and the harness
connector for damage or corrosion and clean or repair as necessary.
8. Use a multimeter (ohms setting) measure the resistance between the ground
terminal (blank wire) and the location ID terminal (pink wire). Resistance
should be approximately 18.8 K-ohms.
