A/C problems

[coreyg67]

Ok, so far I have tried the things you have recommended, with the exception of
the GFI,
but I don't know where it is. 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.
