The Secret 12V Manual Reset - 27' Rear Bath

January 15, 2021, 05:27:39 pm

I kept hearing about this difficult/impossible to find, the 12V Manual Reset breaker.

Looked under the frig, as some had suggested for the MB models. Nope.

After reading a POST from a few months back - one of you scholarly men/woman pointed out that the Reset Breaker was under the dining table seat! What?

Removing the cushion to the forward most seat, I realized that 1/2 of the storage under that seat is covered with a piece of plywood. And, it is screwed down.

Most would say, "why would you put a reset device under a panel that requires you to unscrew it - to view it".

After removing the four (4) small screws, the hold contains a sealed battery box for the house batteries, a junction box for wiring, the secret 12V reset breaker, and a good look at one end of the house fresh water tank.

So here are the photos for those of you looking for this secret Reset Breaker with a 27' (ours is 2010) Rear Bath.

Cheers!

Hmmm . . . wonder where mine is? Thanks for sharing, Tony!

If you folks will send in pictures to this thread of where the reset switch is for other floor plans I will add them to The Companion.
How about Codefour letting me know by DM when the photo set is complete?

In our 2021 RB the breaker is now mounted on the left side rear wall of the battery box. There is no breakers outside of the box. (see photos)

I guess that's why it's secret; it keeps moving around every year.

In our 2011 Mid Bath the breaker is located on the cabinet structural member that divides the refrigerator stack from the stove. It’s rather difficult to access. I ran into it while installing a battery monitor (Balmar SG200).

In the first photo showing the open cabinet under the fridge, the circuit breaker is to the left when looking in. A side panel must first be removed (attached with four screws). Note that in the photo, the back panel is removed, exposing the plastic battery compartment housing.

The second photo shows the bottom of the cabinet structural member that separates the refrigerator from the stove. The white mass to the right is the fresh water tank.

The third photo is a closeup of the circuit breaker. The reset button is barely visible on the left side.

Jim, I took out the drawer above that cabinet yesterday but wasn't able to locate it. Saw a bunch of wiring back there since the battery box is there. I'll have to take another look.

Hi, Greg.

Here's a photo with the drawer out. It's now obvious to me that that's the intended way to access the breaker. Breaker is bottom left in the photo.

Don, here are pictures of the 12V circuit breaker/reset switch in our 2007 TK. It is under the refrigerator on the wall to the left. It can be seen after the large drawer is pulled out from under the refrigerator. The back of the battery box is on the left, the power center is below, and the water heater is on the right.

While these pictures are coming in, I wish one of the electrical gurus would explain how they get tripped.
Simple words, please

and those sending pictures, please say what floor plan it is.
I recognize the one from Jim as being a MB.

And, are 12V circuit breakers GFCI protected?

Only the one 120-volt circuit, controlled through the single 120-VAC GFI breaker, is protected.
I have never seen a 12-volt GFI.

"What is a GFI Outlet?
Short for Ground Fault Circuit Interrupter, a GFI (also known as GFCI) is a type of electrical outlet designed to protect you and your family against electrical shock, fire, and/or fatal electrocution. Your GFCI outlet (receptacle) monitors the flow of current. If it detects a ground fault -- an unintentional electrical path to the ground -- it will immediately cut the power, to protect anyone in physical contact with the electrical system."

12V won't electrocute you. Unless you stick your tongue on both 12V leads it won't shock you (ask me how I know). The 12V circuit breaker is to protect from a potential fire if a direct short occurs and hundreds of amps are discharged into the wiring.

So I looked in the cabinet under the fridge and saw the four screws holding the back panel so I took those off but found nothing. Then I noticed two screws holding in the side panel adjacent to the oven, so I removed those and still didn’t find anything, except where the spiders like to hang out!

I then went outside and looked in the battery box and saw a breaker with a reset button. Is this it?

Excellent idea, Don! I really wish Lazy Daze would not hide a crucial circuit breaker and--worse--not document the location.

Tony, here's a thought: it looks as if it would be simple to drill a hole (maybe with a 1" hole saw?) in the plywood panel right above that circuit breaker, allowing easy access without removing the panel. Then if it were me, I'd put a label on the plywood next to the hole, and another one on the front of the dinette seat above the cat bowls where it would be visible without removing the seat cushion.

I'm a big believer in labeling, because I know from experience that otherwise I won't remember six months or a year down the road. I carry a Brother label maker everywhere I go. You can get these for as little as twenty five bucks, but having tried several models, I ended up with the PTD-600, which has an excellent, highly readable backlit display.

I believe it is. Our's is only 50A. Do you have the Owner's Manual?

It looks like LD finally got smart and put the thermal breaker where is can be easily accessed.
It's something an electrically handy person could add to an older LD, replacingthe hedden breaker.

I do, Charles, but it only mentions the 120V breakers, unless I just missed it.

The last page in our manual is DIAGRAM #5 showing the 12V wiring including the DC Power Contactor, Batteries, Battery Breaker, House Breaker, etc.

This breaker is automatic reset type, normally requires no manual intervention. The only time it needs attention is a serious short circuit occurred, forcing it to constantly trigger. In that case, a detailed troubleshoot is needed to find where is the short in the 12v circuits.

OK, I see it. Says it’s 50 amp and located within 18” of the batteries. I guess they are using a 90 amp now and placing it in the battery box.

Could this have been an undocumented mid-year running change? If so, I wonder if affected 2017 model-year buyers were informed. Seems strange to me.

It is NOT an automatic reset breaker in our 2007, neither 12V breakers are. Where did you get that info? Is yours an auto-reset?

All the pictures I saw today indicated it is an automatic reset type, same as the one in my photo. My 2004 MB is in the same location as shown in the picture posted by Jim, showing it hiding behind the drawer below the fridge. There is NO reset button on this type of circuit breaker. It has an internal electric magnet pull the circuit open when the dc current exceeds 50amp. Then close the circuit when temperature cools down, therefore, automatically reset. This type of ARB (automatic reset breaker) is widely used in automotive industry.

The photo in Jim’s post (reply #5) shows a black reset button on the left side. The Lazy Daze diagram says it’s a manual reset. Am I missing something here?
