Another HWH Leveling System Problem
I have the HWH 625 automatic leveling system on my motorhome. The touch pad does not respond or light up to any commands, auto or manual. The slides work fine and the little light comes on when I ope...

OK, you have NO 12 volt ignition side power to the main control box.
8 PIN BLACK CONNECTOR - CN8 on the plexiglass control box will have pin 6 wire number 6120 (red wire), THAT wire should have 12 volts when ign key is ON. If not, find where Winne connected the 12 volt ignition on the front area chassis fuse block or dash. The fuse holder(HWH) is in the area of the parking brake and dash red down indicator. The odds are it either came out of the fuse block or the fuse for that circuit is blown. Once you find that 6120 wire, jump a 12 volt positive to that wire protected by a 5 amp fuse. Then see if the touch pad comes alive. I bet it will. Then find the problem where Winne connected the 12 volt ignition. If HWH system wired CORRECTLY (most are not) the 6120 ACC wire may be on the Ignition side. The reason HWH has 2 wires at the Dash (Ign and ACC) is, if the system is wired to the ACC, you can operate the jacks system and the down Buzzer will NOT sound when either extending or retracting. The Ignition side is for when you start the engine and jacks are extended you will get the warning buzzer. Most would prefer it wired correctly, where you can extend and retract using the ACC side and not listen to the warning buzzer. Doug
