No problem with it till now. I accidentally reversed pos/neg wires from batt. to converter. Lost inside lights..batt. charger etc. Pos. + wire is dead, but 120 AC worked. So...

Ran new temp. pos. wire from batt. to conv. All lights..charger etc. worked. I do not see any visible fuses for reverse polarity protection.
Not visible is where wires run under/thru flooring? Its 01 Trail lite with underside (belly) covered with metal.

Q..If anyone knows..could crossing wires burn up just pos. wire? I did continuity check..something is preventing it..hard to believe if my pos. wire does have fuse it would be hidden? Anyhow...

Any ideas/thoughts appreciated. TIA.. B.

You should have a circuit breaker on the positive cable. It could be at the edge of the frame or in a junction box inside along the floor and front wall. Good luck in finding it and keep us posted.

RVW..

If I understand correctly..no inline breaker before + connection to conv. would have burned out something? Gonna take harder look for it.

Forgot to mention..what/if any diff. this would make?..after wires reversed..t. plugged into (yes, good one.ha!)my 120V/30A. rv cir. If all else fails...

Will try to pull old/new 13ft. 6ga. wire at same time. If no go will have to get creative. Not familiar with, but will get a new (you mentioned) in line breaker. Tks. B.

RVW...

I found the breaker (shortstop 24VDC 50A) & pos. wires mounted on front inside wall (storage area) underneath couch..same corner where furnace is. Flashlight makes a diff. HA!

Breaker apparently undamaged cause I pushed the little black button..bingo..alls well. Tks.
