I have a 1977 HiLo and cannot get it raised. I think the motor or pump needs to be rebuilt. Is there any way to raise it when the motor/pump does not work and I do not have access to the motor/pump in the down position. Also, where would I find a new or rebuilt motor and/or pump? Or what are the brands and model numbers of the pump/motor? Thanks so much for any help that you can provide.

There are older models here on the forum.
I consider it unusual that there is no access to the pump and motor.

If all is true, I think that the only way you can start is to have some, 4, burly men lift the top and place on stilt legs to gain access. Stabilize very well, and level!

Once accessible start with the least first. Charge the battery, or get a new one, rated for rv's. The motors a very robust and have a long life. But there are other problems that usually are the true culprit.
A multi tester for electrical will be required to test circuits. Check first for current to the solenoid, then to the pump motor, etc., check all fuses in-put and out-put for broken or loose wiring.

Get back to us when you have it up and accessible. We are here to help!
