Why is the motor on my Princess Auto Jacks not working?
- D
  Debra RichardAug 4, 2025
  If the motor of your Princess Auto jack won't operate, start by checking the battery and electrical connections, ensuring a minimum of 10 VDC. If the battery is low, connect the trailer cable to your tow vehicle and start it to supply power to the jack. Also, ensure there's a good ground connection by cleaning the area between the jack mounting plate and coupler, making sure paint has been removed by the star washers for direct metal-to-metal contact. Check the wires on the ON/OFF switch and secure them if they are loose. Wait 15 seconds to allow the internal circuit breaker to close. If the issue persists, the ON/OFF switch or the motor itself may be faulty and require replacement.

What to do if the motor clutch engages on Princess auto TowingMaster 8970220 Jacks?
- A
  Alexis Clark MDAug 18, 2025
  The motor clutch in your Princess Auto jack might engage if the jack leg is fully retracted or extended; simply release the switch when you hear the clutch. It could also indicate a worn gear, a dirty or bent inner tube, a faulty clutch, or excessive tongue weight. To resolve this, you may need to replace the gear or the inner tube, clean the inner tube, or replace the motor. Also, verify that the jack is suitable for the tongue weight you're using.
