Installation
Follow these steps for proper installation of the wiper motor:
- Prepare the Vehicle: Ensure the vehicle's ignition is off and the battery is disconnected to prevent electrical hazards.
- Remove Old Wiper Motor (if applicable): Carefully detach the existing wiper arm and motor assembly. Note the wiring connections before removal.
- Mount the New Motor: Position the Bediffer wiper motor in the desired location on the windscreen frame or mounting bracket. Secure it using appropriate fasteners. The motor is designed to fit Willys Tractors.
- Connect Wiring:
- Connect the positive (+) terminal of the motor to the 12V DC power source (e.g., ignition switch or dedicated wiper circuit).
- Connect the negative (-) terminal of the motor to a suitable ground point on the vehicle chassis.
- The 'S' terminal is typically for the automatic stopper function, if utilized. Consult your vehicle's wiring diagram for specific connections.
- Install Wiper Arm: Attach the wiper arm to the motor's output shaft. Ensure it is securely fastened and positioned correctly for optimal sweep.
- Test Functionality: Reconnect the battery. Turn on the ignition and test the wiper motor's operation using the integrated switch or vehicle's wiper control.

Operation
The Bediffer wiper motor is designed for straightforward operation:
- Power On: Once installed and wired, the motor receives power when the vehicle's ignition is on and the wiper circuit is activated.
- Using the Integrated Switch: If your motor features an integrated ON/OFF switch (as shown in Figure 2), simply toggle it to the 'ON' position to activate the wiper and 'OFF' to stop it.
- Vehicle's Wiper Control: If the motor is connected to the vehicle's existing wiper control system, operate it as you would the original wiper system.

Maintenance
Minimal maintenance is required for the Bediffer wiper motor:
- Regular Inspection: Periodically check the motor and wiring for any signs of wear, corrosion, or damage.
- Cleanliness: Keep the motor housing free from excessive dirt, mud, and debris. Use a damp cloth for cleaning.

Troubleshooting
If you encounter issues with your wiper motor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not operate. | No power, loose wiring, blown fuse, faulty switch. | Check battery connection, inspect wiring for secure connections, check vehicle's fuse box, test the wiper switch. |
| Wiper moves slowly or intermittently. | Low voltage, excessive friction, motor nearing end of life. | Verify 12V power supply, ensure wiper arm pivots are clean and lubricated, consider motor replacement if issues persist. |
| Wiper arm does not return to park position. | Faulty park switch (if applicable), incorrect wiring of 'S' terminal. | Check wiring to the 'S' terminal and ensure it's correctly connected for the park function. |
If troubleshooting steps do not resolve the issue, contact customer support or a qualified technician.
