What should I check if an excavator wiper motor parks in the wrong position or runs too far?
Short Answer
If an excavator wiper motor parks in the wrong position or runs too far, check the motor wiring order, park-switch circuit, arm spline fit, stop position, relay logic, and whether a non-genuine replacement motor uses the same park wiring as the original. JIAJUE checks the motor and wiring together because park faults often come from miswired replacements instead of the linkage alone.
What To Check
- Send photos of the wiper motor label, connector pins, linkage position at park, relay area, and the machine model and serial plate.
- Confirm whether the blades over-travel, stop mid-glass, park on the wrong side, or only fail after a replacement motor was installed, because those symptoms point to different causes.
- Check for swapped wires, stripped arm splines, broken stops, or an incorrect replacement motor before replacing the whole wiper assembly.
