Circuit breaker in battery compartment
We have a 2008 24' Front Dinette. There is a 120 amp manual reset circuit breaker in the battery compartment. Can I use that breaker like a household breaker to interrupt power to the converter compartment? I guess I'll need to do something about the solar panel and the chassis battery while I'm at it. I'm changing out the water pump, and I don't want any surprises while I'm doing that. Thank you.

The breaker in our 2003 FL doesn't have a button to turn the breaker off, only a reset button.
It would be easier and safe to pull the water pump fuse, in the Power Center.

Looking at your photo, you rig looks very similar to our except you have Wrangler, with kayaks.
We often carry our kayaks on the Cherokee, when it's being towed.

Thanks, Larry. I came to that conclusion too after I couldn't figure out how to turn that breaker off. I have a similar breaker under the hood on my Jeep to protect an extra fuse box for all the add ons, but I can turn that one off. I have been considering going to a Cherokee like yours. We've had a couple of them, but my older son talked me into doing  pretty extreme lift on the first one, and now he's put a Golen stroker in the current one. The CJ is a rough riding beast, but it will go anywhere that I can handle. The Cherokee is a much better all around vehicle, and it did very well even when it was totally stock so if I can find a nice one...who knows?

Aftermarket breakers can be made to also act as switches.



If you decide on a Cherokee, look me up, I have a bit of experience with setting them up.

Sorry about the formatting, don't know why I can't fix it.

I'm pretty sure this breaker interrupts the feed from the alternator, not the converter, so it would not do what you want even if tripped.

Steve, please tell me more. I know the coach batteries are charged by the alternator when the engine is running.  So that breaker is to protect the batteries not the converter side?

Technically, the breaker protects against catastrophic energy release by the batteries from causing fire or explosion - i.e. it protects your rig from the batteries. There have been cases where the breaker had tripped, and folks lost charging while driving, and house battery powered items in the cab would not function with the engine off. However, all circuits connected through the converter would still function. LD usually mounts a smaller self-resetting circuit breaker hidden in the run from the batteries to the converter.

The converter fuse block has a fuse that will power the water pump - If this fuse is not so marked, pull and replace fuses with the pump running until it stops.

On my 2004 MB the water pump is fuse #1 on the dc panel.  It's a 15 amp fuse.
