I just purchased a 1975 Argosy 28' pull behind. The interior lighting is
becoming a puzzle. The first thing I did was replace the inverter, thinking
because of the "buzzing" and the red glow from a connection, it had shorted
out. I replaced it with a new unit and still have the same problem. Whenever
more than two (12V) interior lights are operated at full power, the inverter
kicks in and out and at times a "burning" smell comes from the unit. I've
felt the wires coming out of the inverter, and none are hot. If they were
hot, I would suspect a dead short. I've tried isolating connections by
removing one at a time, to try to isolate circuits. It doesn't seem to
matter what circuit I disconnect, whenever theirs a load, the inverter
doesn't seem to want to handle it. Keep in mind I am having the same problem
with the new replacement inverter as I did with what I would guess what
the original installed in '75. To further complicate the matters further
I have tried shutting off specific lights, thinking one has a dead short.
To date, no combination of lights, on or off seem to indicate this. Also,
the inverter is not blowing fuses.  Has anyone had a similar
problem?
