A/C problems

[Wallace Craig]

Corey, I'm sure I have seen your post before and as you can see I am not to far from Prosper. The one person I know that is fully capable is Ralph Fullenwider whose e-mail is "rlf47@swbell.com". He has maintained coaches for me since early 90's and know what he is doing.

There is one in the bathroom, but I cant get it to do anything for me, I'll have to look into it. I have one inverter panel that is reading AC input from the generator, and the HVAC units are running. BUT, when I try to run all 3 is when an overload condition happens on leg 2, while leg 1 shows very minimal draw. I have pulled the inverter for leg 2 out, and have the cover off to see if I can locate the transfer switch. Looks as though it isn't functioning, but I'm not sure how the entire setup works exactly. I can manually change the switch and get the inverter to show DC amps on the panel, but still no AC input. My problem is, the only way I can charge the coach batteries is to run the generator. I don't understand why I'm not able to draw any power for the shore cord. I plan to find a repair facility near me that can help me with some of these problems, so that may be my next task. Although I certainly prefer to do the work myself. Corey & Jenni 1996 PT42' Prosper, TX --- In WanderlodgeForum@yahoogroups.com, "Ralph L. Fullenwider" wrote: > > Hi Corey: > > First things first.
