Happijac beds in garage not lowering
SO I thought I would post this in case anyone has the same issue with their beds in the back of a toy hauler. I brought my trailer out of storage this past weekend. I am going camping this weekend so Ive been going through it getting everything ready. I went to lower the beds in the back and fond they wouldn't come down. They would raise up and finally got to the point where they wouldn't move at all as the upper bunk hit the limiting switch.
I found instructions on their website of things to check. I tested the switch and lower limit switch. Both worked as they should. Obviously it had power as the bunks did move up. I finally reached up and released the brake so the beds came down. I hit the switch again and now the bunks wouldn't go up or down. Tracked down the fuse and it was blown. SO I replaced the fuse and was back to the beds going up but not down.
I checked the connections at the module and motor and they looked ok. Put everything back together and won't go down. I grabbed a phone cable to test the connection between the switch and module and still no change. I then decided to unplug the limiting switches and no it wouldn't move. Plug them back in and found the wires have to be a closed circuit for the bed to move. So I jumped the one set of terminals and bed moved up. I then jumped the terminals on the other set and the bed moved down. Ok maybe the wires between the module and lower switch were bad. I cut off the connector and joined the wires then plugged it into the module therefore bypassing the witch and wiring. Bed wouldn't drop down again.
It turns out that the little crappy connector that plugs into the module was the issue. If I just join the the terminals together the bed now works just fine as it did before. I will now make a proper pigtail at work and get rid of that junk they use. Simple fix.
