Clicking sound from where home battery is.

It’s unlikely it has anything to do with which leg of your trip you were on.

Assuming it’s one of those CB’s tripping and resetting, it’s going to take some knowledge of the circuits each one is protecting in order to test each one. Your owners manual may have that info, but don’t be surprised if it doesn’t.

As new as this unit is, I would be checking into getting Coachmen to authorize warranty service at the closest, most convenient location to you, or even a mobile RV service tech. I’m of the opinion that electrical problems shouldn’t be ignored.

That yellow with black-stripe wire going to the item I marked #2 isn’t pinched under the seal and anything metallic, is it? Just wanting to make sure.

No that wire isnt pinched or anything it looks like they are all secured as well. i did have my refrigerator runnign though so i am going to turn it off and hope that was the issue when we leave here tomorrow for texas.

#1 looks like a maxi fuse holder. There should be a replaceable fuse under the cover.

#2 I think is a solenoid, possibly to isolate the house batteries from the starting battery when the engine is off.

#3 looks like four self-resetting CB’s mounted with the “cans” down and the terminals up. To a plastic holder maybe? Hard to tell through all the paint. No, that’s got to be a +12v buss bar, only one of those CB’s has two cables attached to it.

If those are CB’s, any one of those could be tripping due to a problem somewhere, then resetting, then tripping again, etc. That would sound very much like a turn signal flasher.

Is this something that could possible only have happened on that leg of the trip, i actually wont be where i can get this addressed for about 3 more trips. Unless i need someone to come out and look at it before hand ill have to find a way.

So I'm in a 2021 coachmen leprechaun 300BH, water heater is on the other side of the coach and the propane was on. that's what I was thinking but the fridge should be able to run off the coach battery when im driving right? and it was in auto position so maybe something was going on and it was trying to switch to propane just not working.

Only if you have a three way fridge, and they are not particularly common. Most three ways have a separate button to turn on the 12v heat element control. If you set it to auto, it will try to go to gas when you remove shore power.

I would never recommend for anyone to run in the 12v mode of a 3 way fridge , the amp draw would be in the 25amp range opposed a compressor type 12v fridge at 2 or 3 amps.

FYI, our BIM in our 2016 Sunseeker is in the stepwell; it looks like this after removing the cover:



The guide is on the back of the cover:



There are several relays in this box including the large relay used to connect the chassis battery to the house batteries.

One thing I learned when troubleshooting a lack of charge from our chassis while underway was that anytime the ign key is on, the awning and slides are locked - they cannot be deployed underway.

Do you have a BIM ? A battery isolation manager charges both chassis and coach batteries by switching back and forth , alternating the charge from one to the other. Maybe you are hearing the solenoid clicking.

Im really not sure, but there is something located right next to the battery separated by a compartment under the stair where the battery is located. it does seem like its something related to that since it sounds like an electrical issue.

I agree electrical , but what do I know , I'm not by any means a mechanic I only have a basic understanding .
You're under warranty ? Give your dealership the chance to help you.
What they are using in rvs these days to charge a 12v system is anybody's guess.
***Next to your step, look for an access panel with a few screws that you can unscrew. Behind this panel should normally be the solenoid of whatever type of isolator you have. I had a BIM system by Precision Circuits. This is the solenoid that you might be hearing click on/off. You should hear it click when you push your emergency start switch, if you have one.

If you have a PC BIM.

The BIM could be bad, mine went on vacation right after the warranty ended, it's sensitive digital circuitry.
The company PC was very helpful. The Tech was very helpful to me explaining a lot and had the time to chat.

Some pictures of what’s in and around your battery box would help. There are enough experts on here that can identify what each component is, and what it does.

If you’re unfamiliar with posting images on this forum, use this site. It’s pretty easy, you’re just uploading your image to the hosting site (Imgur), and copy/pasting the provided link into your forum post.

Self-resetting CB?

:):)

not sure but my circut breaker box is under my bed in the back. there is a part that is located next to the battery that may have been making the noise but im not sure.

Self resetting circuit breaker is located near the battery and looks nothing like a regular circuit breaker. Google search should give you a good picture.
