Inline fuse

[Terry Bruce]

I have a 2018 1/2 FR Sierra 379FLOK. I tried to hook up what’s called a “Liteswitch”. I have no power at the 7pin connector, but the switch works on other campers 5er and TT. I need help from someone who can provide pictures of where the inline fuses are. I have searched around the batteries, inverter, and 7 pin connector. There no breakers tripped or fuses blown inside the camper panel. Thanks!

There may be a circuit breaker where all the heavy positive wire connect and go away. Find that and look for the little push button on a side.

I see an optifuse with a red button that is OUT. I also see a high amp buss box but no buttons.

Follow the wires from the battery, Maybe near where the Jack's are and where the cable ends that plugs into the 7 pin on the truck. Should be a resettable circuit breaker there. It will have multiple heavy wires on either side of it and a reset button on an end. Very small button.

Thanks. I’ll look again tomorrow. I may need to message you again if you don’t mind. I don’t think I mentioned but it’s a 5th wheel if that matters.

I'm assuming the Liteswitch you are referring to is the device that plugs into the R/V's 7 pin plug and allows you to light up your marker lights?

If so, you might have shorted something out if something wasn't right with the plug wiring or the device.

Do you have a multimeter and know how to use it?

Many of the 12v circuit breakers referred to by A32Deuce are inside the front compartment on a 5th wheel.

Thanks. The Liteswitch works on other campers. I don’t see any circuit breakers inside my compartments, could be I’m looking in the wrong place.

It looks like a small junction box with 2 studs and wires connected on either side. Maybe an inch wide by three quarters high by two inches long and one end with a very small black button to push in. Very easy to overlook.

I’ll check tomorrow. Thanks!
