I am working on a 2000 Georgetown and there isn't any 12 V on the Red wire feeding the front A/C unit. So naturally the heater doesn't work as well.
The 2 feed wires are White marked -12V and Brown marked +12V. (Cap Spliced) I opened the circuit and fed 12 Volts from the battery to the A/C and everything works as it should.
I put a wire tracer / toner on the Brown wire and I can't find it's source anywhere.
I just replaced the corroded battery controller board assembly so I know there isn't any brown wire coming from there even tho one pin is labeled Climate Control. The BU monitor is working so there is juice there. The wire pair disappears up into the overhead and there is a hint that it might be coming from the front.
Does anyone have any idea where the Front A/C unit gets it's source power? There would have to be a fuse somewhere. I hate to imagine opening up the upholstered overhead just to trace the wires. I can temp power for an upcoming trip but I hate Kludges . Yes I would install an inline fuse in the temp jumper. I would much rather fix it properly. Help Please!
Yep I am trying to find the 12V dc feed for that A/C unit..
I checked all the fuses in the panel.
The 2000 model has them below the drawers on the right hand side of the bed. I removed the drawers and used a (Fox and Hound) tone tracer and expected to locate a brown wire in that harness behind the panel but not a peep. I even pulled each fuse and checked it for continuity and they were all good.
The breakers are all for 110 Vac so it isn't any of them.
Thank you for your reply, my hunt goes on...
Thanks for the replies guys but I am way past the basics here.
Let me try asking this question another way. ;-)
Does anyone know where the 12Vdc fuse is located for the front A/C unit on a 2000 Georgetown? It does not appear to be in the main rear panel beside the bed.
It also does not appear to be one of the fuses on the battery combiner unit.
The battery disconnect is accomplished via the battery controller and the use-stow switch by the stairwell. I have 12 Vdc to everything else in the coach.
