Happijac Issue -- Intermittent
We have Happijacs on our camper -- this past weekend, there were intermittent cut-outs when running the jacks up/down. This is the hand-held controller: The yellow light would come on almost...

I'm the OP of this thread, and have a strange follow-up.
I found a new 'coiled' telephone cord, and decided to try it with my Happijac system. Removed the old coiled cable and installed the new. Even though the wires appeared the same colors and in the same order, the hand controller was now as dead as a door-nail -- none of the lights would come on and it was utterly unresponsive. Tested the new coiled cable on a telephone handset indoors and it worked perfectly. So apparently the Happijac coiled cable is specialized and can't be replaced with the coiled cable from a telephone.
But that's not the strange part. Looking at the original cable, there was some slight oxidation to the 'hand controller unit' end contacts. Used a fine wire brush and some WD40 to clean it, re-assembled, and not much difference. The hand controller was still intermittent. So just for the complete, sheer hellavit, reversed the cable, so the recently cleaned end, was now plugged into the electronic controller box and the other end of the cable -- protected since 2006 in the camper basement -- into the handset. The intermittent behavior immediately vanished and the system has worked perfectly since.
This is bordering on voodoo... Go figure...! :?
