Battery Disconnect

[SoldRV]

Hello everyone, I recently removed my battery disconnect switch and when I plugged it back in there is no power. Seemed to work perfectly fine before unplugging. Not sure where to start diagnosing this. I’ve checked for blown fuses but haven’t found any. Any help is appreciated!

I'm curious why you removed it...were you having a problem with it?

There very well might be an inline fuse between the battery and this devise. Might look something like this

I removed because I am remodeling and decided to have it completely out of the way so I didn’t mess anything up accidentally, little did I know… haha.

Thanks SpencerPJ, I’ve never encountered a fuse like that, is there a way to test if it’s bad? Do I just hook a multimeter up to both sides and see if there’s current?

Looks like there’s some of those inline fuses here. No idea on how to see which one though or if it’s the right area.

Yes, it is a simple break in the circuit. Mine, albeit a Travel Trailer, is about 5 feet downwind of where my positive connects to the battery. Keep in mind often RV 12vdc wiring, black is +, and white is -, so assume nothing. A meter will be your friend here, even just checking continuity.

Thanks for all of the replies, I finally found a manual online and was able to determine there are two 5amp fuses connected to/around the relay (in a very not so easy to see/reach area) and both were blown. After replacing, all is back to normal and switch is operational again.

For reference for others, this is the same relay as the one in the pic above, if you click on the pic and enlarge it, you can see the two fuses (blue arrows) peeking out from behind the gas tube (I need to make a better pic next time I am in that area.)

I have since sheathed the gas line in plastic split wire loom material (Harbor Freight or auto parts stores)

Probably touched a wire to ground while the switch was out. Happens to all of us at times. That means that the fuses did their job and it is better to replace a couple of fuses than what they protect.
