When the disconnect is pulled out (turned off) what electrical equipment should work inside the camper, 12V, 120V, or NOTHING? When my switch is pulled, everything works as normal. The wire leads are connected to both terminals of the switch. Maybe I have a bad switch? Lakeside

If your battery is disconnect and you are not hooked up to 120 volt power nothing should work.Switch is either bad or not hooked up properly.

Don't know what FW you have, but the disconnect switch should kill most everything inside. A few emergency things, such as LP/Co detector, emergency weather radio may still work.If actual battery cable is disconnected, nothing will work. Above assumes you are not plugged into shore power.Jerry

First off if the trailer is plugged into 110volts all systems should work. If not plugged in to 110volts only the 12 volt systems will work until the battery disconnect is turned off. If wired correctly all 12 volt power will be removed from trailer.

On my 2015 Winne the electric step is still powered with disconnect switch off.

If I were to check latest RV building regulations, likely the break away brake switch should always have power. I could easly fix that, but because I need on to run the landing gear, I have turning it on covered. It for sure disconnect all parasitic draws CO2 and propane detectors as they are what will draw the battery down over time.
