I had a low voltage occurance, found the motor in the stowed position with the power light lit and an alarm beeping. I found the magnetic pickup out of place, reinstalled. Replaced both 12v batteries and the cr2450 battery in the remote. I have 24v at the power cable plug. Battery ind. shows 100%. The remote will come on for 3 seconds and then off. I’m hoping for help instead of replacing everything one piece at a time.
