Battery fuse lication

Can somebody tell me the location of the fuse for the batteries on a 2025 Avenue 332rl. I know it’s in the utility bay but after located how do I tell if it’s bad or not

Morning, would be able to be a bit more specific with your request.

Many units don’t have a “main” battery fuse, but rather a 12v fuse panel that contains many fuses.

Checking a fuse really depends on the type. Some can be checked visually, some would be best checked with a meter.
A lot of our fuse panels have lights on them that come on when the fuse blows.

If your looking for a main battery fuse, just locate your battery and start following the larger red cable or cables until you find one.(if you have one).

If you have a main battery fuse and it was blown, nothing on the coach that is 12v would work if blown.

Are you chasing a specific problem?

Hey there. I have a 2026 Delta 262. And my battery is not charging while on shore power. Battery is almost dead. 50 amp shore power is good on both legs.

When connecting the battery, I inadvertently connected the wires backwards (master power switch was off), however, I reconnected them properly before turning on the trailer master power.

Did I blow a fuse somewhere? If so, where would that fuse be located in my 262? Also, I'm using a lithium battery, if that matters. Thanks all

@Ox262 My converter has Reverse Polarity fuses on it. It's possible you fried those.

I agree with George, check your converter for reverse polarity fuses, you likely blew one or more.

Where are they? My panel is a separate Dc and separate Ac. But no fuses are labeled reverse polarity

Would you be able to post a picture of your panel? Or share the make and model of your Dc panel And converter?
Perhaps you have a different style converter and they are contain within it.

These would typically be heavier fuses @ 25 amp .

Thanks everyone for the help. It's the end of the day, I'll dig deeper tomorrow. Alliance tech is also working the problem

I just reviewed the Delta’s owners manual on their corporate site. Your reverse polarity fuses are most likely located on the converter itself according to the model reference in the manual. Should be an easy fix once you locate the actual converter.

Alliance said the RP fuses are on the converter, located on the back of the breaker panel. Tomorrow I'll unplug from shore power, and pull out the breaker panel and see what's up. Thanks.

I did blow the fuses when I accidentally connected the battery, even though the trailer master switch was off.

The blown fuses are located on the converter. I had to remove the breaker panel, pull it out of the way, then remove the converter box and the 35amp fuses are located on one end.

In hindsight, I should have removed the fireplace. I think that would provide easier access to the converter.

In the end, all good and a great learning experience. Photos attached for anyone in the same situation with a Delta.
