Troubleshooting Hints

IMPORTANT: To avoid misdiagnosis, check linkage for mechanical binding which would prevent correct system operation.
1. Check Fuses 6 and 19.
2. Check that ground G304 is clean and tight.
3. If a motor's internal circuit breaker trips, it will not reset until voltage is removed from the motor.
4. If system checks OK electrically, refer to Brakes and Traction Control for hydraulic system diagnosis. Brakes and Traction Control
- Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
- Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (refer to General Troubleshooting Procedures). Diagnostic Aids
- Refer to System Diagnosis.
