I'm sorry I didnt mean to not post what was wrong. The battery system we figured out, and we got the generator working. What's still a mystery is the Norcold refrigerator that doesnt get cold or anything. It runs on propane or electric but we cant seem to get it to turn on and work. I also need 2 tires, after I got to my rv park to stay for a few months, 2 tires magically went flat. Well one tire blew up and the other tire I think was slashed, so I really need to know what tires to get the tires currently on the RV in the front is LT 235 85R16 xps R18.
Right! I'm sorry to have totally missed the idea! My first picture was of somebody totally getting a potential nightmare as an old RV can really go downhill when not watched, so if you are just having a few troubles, that is GOOD!

A tire question and a frig that needs a look gives much better odds!
If you can find a label on the frig that gives a specific model number, I like to look at drawings and go at the repair with more info from online manuels, but if the model number is not handy, there are some common things that do go wrong with the common frig.
I assume you mean it SHOULD work on electric and propane but doesn't?
That probably means it normally goes on 12VDC or propane and when both fail, it may lean toward being a power problem as the 12VDC is needed to operate things even when turned on propane.
Do you have any lights on the front of the frig?
One quick check is to make sure the wires to the back of the frig are clean and connected well as that is a common problem. Need to verify that 12VDC is getting to the board on back as it might be a fuse or simply corroded wires.
We can get a better idea with the model number, though.
