Wife turned it off and a cupple of days later she went out and turned it back on, nothing she said happened but for getting a shock when stepping into the rv so she unplugged the rv. I got home and checked it out. Plugged in rv and shut off breakers for air. Everything good. Called a ac tech and he unhooked all the ,switches, relays ect in unit and said he would be back.. well never came back so I am stuck not knowing where all wires go. Anyone have a pick of wires for ac? There is no board, just a bunch of relays, switches, ect.. I am back on the road for a few days so I can't send a pic of my unit.. any help will be greatfull.

Start a new topic for your specific problem. You will get more replies and therefore more info. Many people do not read new replies to old topics. Either the topic is not of their interest or they figured the problem has been solved and there is no need to follow old topics.

Good day. I bought a 94 vectra motor home that needed some wiring,plumbing, repairs from sitting for 3 yrs. The unit is fixed but for a new problem. The basement air conditioning, I had it working for weeks this summer and while I was out on the road, my wife said it would not come on and she got shocked waking in the unit so she unplugged it. When I got home I plugged it in again and turned off the air, I had an air conditioning guy come outo and look at and while there he unplugged some of the replays, switches and left. Never to come back. Now I have no where to go to find where these wires go. I found a 110 wire that was rubbing in the frame and fixed it so hoping that's was the shocking problem. Does and one have a pic or wiring diagram? Would help me out real good. It's a great unit and would love to have the basement air running again.. thank you

Thank you so much for the info.I have heard that you can wire up unit for 1 compressor? Would you know how to do that incase I can't get both running again?

No re-wiring required; each compressor is on it's own separate breaker. Compressor #2 will not run unless #1 is already running. Simply turn off the breaker controlling #2 compressor.

If #1 compressor quits, then re-wiring is required to switch wires from #1 to #2 compressor and leave #2 un-wired.

FWIW, one compressor will NOT cool the MH significantly , it may maintain set temperature, but not lower the temperature a noticeable amount on a hot day. What effectively happens is, you are running one 12,000 BTU air conditioner on a hot day for the MH.

Big Red Pete; My reply should have read "leave #1 unwired", my bad.
