Jim_VaBeach, Howdy;
Several threads on this one ....
Long story short .... Go to the outside access panel,
inside look around and you'll see a small Black Box,
inside it are 2 automotive (Glass cylinder style). fuses.
One is for the 120vac side It's a 10 amp.
The OTHER is for the 12vdc side AND is the primary power
source for the whole she-bang.
If that's not the problem I'm outta ideas...
and you'll have to use the search function in the toolbar up top...
