Two battery disconnects

caroleemoreno · 10-13-2023, 07:06 PM

I just noticed that my Salem FSX has a second battery disconnect on the underside of the trailer frame. Pretty much on the opposite side of the disconnect located on the outside of the trailer. Why are there two? And do they both perform the same functions? I have no idea what the one on the underside of the trailer is for.

Never heard of any trailer having two factory battery disconnect switches.
Pics are often more helpful than descriptions.
Did you buy this trailer new or used?

Bought it used, only a year old so doubt any prior owner modifications, they only used it one time. Outside disconnect is mounted on the trailer frame behind the propane tanks and has the little key, and directly on the opposite side of the trailer frame is the knob type disconnect. They line up perfectly so it almost seems to me that it is some kind of dual switch that allows you to kill the power from either outside or from underneath if you need to. Wish I could provide pics but the RV is in storage right now. Just wondered if this was some kind of Forest River thing as I have not ever seen switches mounted back to back like that. I will look at it closer when it stops raining and I have some daylight. Maybe they put one on the positive side and one on the negative side? It’s mounted right near the terminal blocks . Can’t say I even noticed what color the wires were going into it. I haven’t even had a chance to turn it on and see if it kills power.

I'm guessing that the previous owner either had a second disconnect switch installed, when they bought it or they installed it themselves.
Never heard of any trailer, from any RV manufacturer, that installs two separate battery disconnect switches.
