Bob52 Posted August 19, 2015 Report Share Posted August 19, 2015 My Happijac's are working backwards for some reason. I pushing the up button on my remote and it goes down. Must have a safety switch on the slider because my jacks only work when my slider is out. It would be much safer if the slider was in when lifting.Model of jacks is 4150. 2005 Host Bachelor SS Truck Camper, ultralite Aluminum Frame, Double pane windows, One Piece TPO Roof, 40 gallon fresh water, 40 gallon grey water, 30 gallons of gray water, Roof ladder, 34,000 BTU furance, 6 gallon DSI Gas Water heater, Built-in interior Entry step, Dinette Slide-out, Electric Jacks with remote, attic fan, Winterization system, all season, Link to comment Share on other sites More sharing options...
Ronbo Posted August 19, 2015 Report Share Posted August 19, 2015 Something is wired backwards. If you have a main relay for that system you might check those wires. I have a level up sustem and if I get in a situation where the angle is too great I have to switch the wires and push extend to retract the landing gear Ron C. 2013 Dynamax Trilogy 3850 D3 2000 Kenworth T2000 Optimus Prime Link to comment Share on other sites More sharing options...

They worked fine. I just bought this a few days ago. Then when I worked the remote I couldn't get the Jack's to work so I was pushing every button on the remote and found out my slider was the problem. Slider has some safety switch to prevent people from lifting camper when the slider is out. Problem is now the jack's work with the slider is out only. 2005 Host Bachelor SS Truck Camper, ultralite Aluminum Frame, Double pane windows, One Piece TPO Roof, 40 gallon fresh water, 40 gallon grey water, 30 gallons of gray water, Roof ladder, 34,000 BTU furance, 6 gallon DSI Gas Water heater, Built-in interior Entry step, Dinette Slide-out, Electric Jacks with remote, attic fan, Winterization system, all season, Link to comment Share on other sites More sharing options...
oscarvan Posted August 19, 2015 Report Share Posted August 19, 2015 Hmmm, something is not right. Time to trace the wiring. Previously a 2017 Forest River, Berkshire 38A, "The Dragonship". https://dragonship.blog/ Link to comment Share on other sites More sharing options...
Kirk W Posted August 20, 2015 Report Share Posted August 20, 2015 Hmmm, something is not right. Time to trace the wiring. Absolutely! For us to give an answer would be only guessing. With the interlock working that seems to indicate that there is more to this than meets the eye. Could you have the polarity of the 12V system connected wrong, as a DC motor will turn backward when polarity is reversed. Good travelin !...............KirkFull-time 11+ years......

Bob52 Posted August 20, 2015 Author Report Share Posted August 20, 2015 I found the problem and it works now. I cleaned off the battery connections and it works again and this time the slider is in the camper instead of out like before.

Fulltimer51 Posted August 21, 2015 Report Share Posted August 21, 2015 On my BigFoot system, If I want to raise the rig I hit UP. If I want to lower I hit the down button. Since the jacks work opposite from the way you want to go, I dont find this to be incorrect. I guess it all depends on how you look at it.
