WHEEL DRIVE TROUBLESHOOTING GUIDE

Problem

Possible Cause

•

Wheel drive motor will not run in forward and reverse.

•  Wheel Drive Motor Circuit Breaker (F3) tripped (reset 30A circuit breaker)
•  Circuit Breaker for the Control Circuit (F2) tripped (reset circuit breaker)
•  Defective Wheel Drive Motor (replace motor) *
•  Defective Throttle Potentiometer (R1) (replace) *
• Replace the

(A2)

Speed Control

•

Wheel drive in one direction only, loss of either forward or reverse.

•

Test the Fwd and Rev

(R1)

wiring outputs (pins 3, 4 and 13) at the speed

control for an open. Repair wiring or replace the R1 pot.

•

Controller can’t change electrical polarity to wheel motor. Replace the

(A2)

speed control.

• Display LCD panel

shows an error 03 fault code.
