Wow you guys are fast! The
fridge was off (12v), it works fine on 12v though (I've tested it parked). The fuse that blows is always the hallway, porch and
fridge circuit. I've gone through 7 fuses, 3 of those were with the old
porch light before/after a couple cleanings (happened after a rain, parked), 2 more of them were after I installed the new
porch light and during a variety of applications of caulk (parked), and the final 2 happened going and coming back from my weekend destination. I'm convinced that the first 5 were the result of rain because they happened very shortly after it rained and it would work for days/week up until then. The fuse has worked while parked for weeks now through some really nasty torrential rains since I did a more extensive caulking job on the new
light and switch. The week after next I'll be hitting the road again and I'll disconnect the
fridge and try that, if I still get a short I'll probably replace the circuit for the
lights (adding a new fridge coil fan on the circuit) and run a dedicated line for the fridge at the same time. I'll look into moving the wires to a new circuit on the fuse panel and possibly might do that if the fuse blows with the fridge offline. I'll post my findings!
Thanks
