I have a feeling that what Doug said is right, but all day I couldn't locate any kind of sign of a switch or fuse anywhere. This has me puzzled.
I have done some work recently with 110 outlets but just simple stuff in the 110 service panel only. If I yank on the wires I can hear them up by the ceiling behind the wall. From this point forward the upper cabinets are installed. The only heavy gauge black and yellow wires that come into the service panel area are not related to the happijac toggle which leaves me to believe they spliced the wires to a smaller wire and so far I cannot figure out which ones they are. What Doug says makes sense, but I'm convinced that something got buried, ....since the happijac relay board has a 15 amp self resetting fuse, someone decided it was ok to bury a common fuse in the wall somewhere behind the cabinets. This is starting to consume all my thoughts. I spent the whole day cleaning my camper and thinking about it and rushing around everytime I thought I had a good idea about what might be happening. I'll probably dream about it tonight. I have not replaced the battery lately.
Monday I will contact Play-mor. Thanks for the info.
