Well this morning we went back to finish cleaning and had no ceiling lights or HVAC ! All the wall outlets work but no 12 volt lights. I had a new battery installed when I bought it and when I checked it, it was dead. When I hooked up my battery jump box the light work and so does the HVAC.
I checked all the fuses and breakers and everything is good. Also checked the 50 amp plug outside with a meter and it is good.
I am quessing that the converter is the issue but have read that there maybe an inline fuse.
Any and all ideas are needed.
Another common occurrence in battery replacement, is to hook the wires up backwards (even for an instance).....thus instantly blowing the reverse polarity fuses to the converter. This happens a lot. The reason for the reverse polarity fuses is to keep from damaging the converter.
I would advise looking up your converter model and seeing if the reverse polarity fuse(s) are on the converter or on the control panel.
If the converter isn't working (or you have no DC power once the battery is drained), then you also won't have AC/Furnace since the thermostat is 12 volt DC to control these. The converter is also what provides 12 volt power, as well as recharges your battery when hooked to 120 volt shore power.
Page 3 of the following link may help explain it better:
If they are on the main panel as in the pic below, it will probably be the two bigger amp fuses (40 amp) to the left of the others, as shown in the pic (which you can read above the fuse that states it's a reverse polarity)
