I need some help with an electrical issue. I'm stumped and apologize for this monster sized post.
I bought a used 2007 Fleetwood Excursion 39V from DeMontrond RV in Houston several months ago. Prior to delivery their new porter decided to wash the inverter as he was cleaning up the coach. No BS, high pressure water straight on it. Needless to say it was toast. They replaced the old inverter with a brand new Magnum brand inverter. Score one for me...
During delivery and signing paperwork I failed to check ALL the electric plugs. No excuses but it was a REALLY long day. So, of course, when we used the coach the 1st time we had plugs that didn't work.
I didn't feel comfortable working on the coach, although I've done extensive remodeling in my S&B, to include electric. So, I hired a RV tech to come by and fix my problem. $177.50 later the diagnosis was a defective inverter. So I called DeMontrond and took the coach to Houston to be fixed as a warranty item. About 3 weeks later my coach was ready with the diagnosis that the inverter was fine and the culprit was a jumper wire in the inverter that was not correctly installed. No charge to me and my salesman filled my diesel tank. And of course I didn't check their work and I still have non-functioning plugs.
My inverter, from what I can decipher, has 2 legs feeding a GFCI outlet in the kitchen and a GFCI in the bedroom, those then feed the peripheral plugs. The bedroom GFCI was non-functional when I got the coach back (functioning prior to DeMontrond trip) and I ended up replacing it. The supply feed off the GFCI was not even hooked up so I hooked it up when I installed the new one. It is wired correctly and works, tester shows it to be wired correctly also. This appears to be the supply for all the non-functioning plugs.
On non-functioning plugs my tester shows hot & ground reversed. I replaced 2 of these plugs and they are wired correctly and all wires are tight. There is just 2 outside plugs left that I have not visually checked or replaced.
Any suggestions besides the obvious inspect or replace the remaining plugs? Monetarily it will be cheaper for me to have the RV tech come out vs a trip to Houston.
