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?

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

No 12v power. If you are not plugged in to shore power, your battery is dead. If you are plugged in to shore power, your converter is not putting out 12v and your battery is dead.

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

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.

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

Happy to be of service.

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

A lot of RVs have the converter connected to a shared circuit. I don't like that style of wiring.

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

You might want to do an Equalization Charge as well

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).
It is someplace well hidden with no access and I'll have to remove some wall panel or shelf to get to it.

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.
