I've got my 2007 21'
Bigfoot jacked up in the yard. I'm rewiring the electric
brakes. I came out this morning to find the outdoor bulb burned out and the plastic cover melted!
I checked the voltage just now. It's 13.75v. The trailer is plugged into 110v and detached from the tow vehicle.
Battery is attached.
Reason for brake work: Both right side
brakes were not engaging so I attached jumpers from the front left brake wires to the non-functioning front right brake and immediately all four
brakes function. So my bad wire is discovered. I'm waiting on 10ga wire to rebuild the entire harness. So - that's the only
electrical work going on with this trailer.
I put in an LED into the outdoor socket. Of course it
lights up fine.
Any ideas what happened? Can old bulbs just overheat like that or did there have to be a current spike? There's no tow vehicle attached so little chance the brakes could be even activated - and why would the brakes even effect this one bulb? Other electrics function fine;
fridge,
lights, pump etc.
