Possible causes:
The origin magnet is missing or incorrectly mounted
Possible solutions:
Check that the magnet is still mounted on the gate and that the gap between the magnet and the sensor is minimal. Refer to Figure 1 on page 2
Ensure that there is an audible ‘click’ whenever the magnet passes the origin sensor
Ensure that the arrow on the magnet is facing the operator – there should be a repelling action when the magnet is brought near the sensor
Ensure that the battery terminals are properly connected on both the controller and battery side
Measure the battery voltage – it should be no lower than 11V DC when placed under load.
Check for corrosive build-up around the battery terminals; if there is corrosion replace both the battery and battery terminals.
Replace the battery
Measure the onboard charger’s output voltage. It should be about 14V DC with the battery disconnected
