3 position switch to the inside of the door
 

Inside the door are 2 switches (1) the whiote switch raises and lowers the camper and (2) the 2nd switch is a 3 position switch - what is operated in each of the three positions? Thanks, Please respond to ronniebailey@windstream.net

If your's is like mine, the brown 3 position switch operates like this. If the switch is pushed in at the top, it puts electricity to all systems in the trailer, except the top lift system.

if it pushed in at the bottom, it cuts electricity to all systems except the refrigerator, and powers the lift system.

If the switch is centered, then electricity is cut off from all systems except the refrigerator.

There is a large reference library here on the forums, as well as a place to make library requests. Perhaps you can find a copy of the owner's manual for your hi lo.

What year and model do you have?
