Up switch just buzzes. Tried new battery and jumpers. Could it be the solenoid?

Try jumping the solenoid to by-pass it. If the top raises, replace the solenoid.

Thanks, but top is down and getting to the solonoid is difficult. is the selonoid replacable? Can the top be jacked up without messing up the cables?

Thanks again, Don Worrall, Sonoma CA

The top can be jacked up but must be done only a few inches at a time, at the 2 front and 2 back positions near the frame, too much at any one place may brake the glide blocks from binding. Only go as much as needed to get at the solenoid. The solenoid can be replaced, any auto parts should have a substitute, or get one from JR Repair.

Thanks Pop. What kind of jack do you use use? Do you use two? Is near the frame where the guides are? Do the cables get slack and come out of the lifting wheels? Could you email me? dtndmw@aol.com

Thanks, Don Worrall

What year and size is the trailer?
