12 volt DC problem

Last night my 12volt lights went dim and the big long motor operated awning came in at a snails pace and I thought it was going to quit.
This morning, none of the 12 volt dc is working.
As soon as it is light out, I'll check the battery, but if it is not that, what should I check next?

On another note: It is unbelievable to me that they mounted the open electronic board with a gazillion wires and electronics that controls the slide, the tongue jack, the awning and the stabilizers directly under the bathroom sink trap, faucets and water pipes with only a thin 1/16" shelf panel above it and no other enclosure

You would be surprised the junk they put together and shortcuts they take to save a few pennies.

Any one with a 37 foot Forest River Wildlife trailer with a 50 Amp service know where it is ?

Turn on many 12 volt items and listen for the fan.


Thanks, good thought !

I have already heard the fan and it is evidently mounted behind the distribution panel. The best way for me to get at it, (if and when I need to) is to remove the bottom shelf in a closet it above it.

I re-wired my panel and put the converter on its own breaker as shown in this video


Mine is on a separate breaker, but when and if I ever have to get at the converter/charger, I'll have to send out a search party. It is a 50 amp one and is a stand alone one (not under the distribution panel like the 30 amp ones).

Happy to be of service.

After the battery is fully charged, get it load tested. Taking a battery down that low can kill it.

Could be no power from pedestal. (Power outage or breaker tripped.)
Could be breaker tripped in your RV. (Main breaker or breaker to converter.)



God bless you and many many thanks!
I never even knew there was a 120volt breaker for the converter.
Several days ago I was working on some 120 volt stuff and by mistake shut off the wrong breaker. I corrected myself but never thought to turn the first breaker back on.
After your reply, I just went and looked at the scribbling on that first breaker and sure enough after figuring out what it says it looks like "conv"
All is well and you just saved me a bunch of bucks.

Thanks again

Battery is dead. Time to charge it. If you are plugged in to 120vac power, then for some reason the battery isn't charging.

Need more details in order to help diagnose your problem.

if this is an MH did you accidentally turn off the battery disconnect?
