Under normal conditions, installing a complete wiring harness requires approximately 4–6 hours with two mechanics working together.
Common signs of wiring harness damage include:
- Drive motor solenoid not working
- Walking speed switching malfunction
- Fault codes that appear or disappear when walking or shaking the wiring harness
To confirm excavator compatibility, verify the following:
- Whether the circuit functions are consistent
- Whether the number and arrangement of plugs and pins are consistent
- Whether the electrical voltage parameters are matched
HEUI (Hydraulic Electronic Unit Injection) systems are extremely sensitive to contamination — a single speck of dust can cause premature failure.
- Connect each plug of the wiring harness to the corresponding hole on the test bench
- Each time a switch is turned on, a function is tested; the corresponding indicator light turns on, confirming the function is normal
