Battery issues

[Meadows11]

The battery is fully charged, but I have no power to the camper on battery. What can be the issue? I have a 2018 Jayco 25BH.

Do you have a battery disconnect switch? Red, sometimes with a handle, switch that says on/off? If it's off then that's your problem. If it's on, it's possible that it is bad. Could be located near battery compartment or in the propane storage space, or prehaps the passthru.

Safe Travels!

After seeing your "red box" post and in addition to Clarkes suggestion, you may also have either a tripped thermal breaker or fuse. This can happen for a number of reasons including connecting the battery cables to the wrong post creating a reverse polarity situation.
You should have two maybe more of the thermal switches and are usually covered with a red rubber boot. They look like this:

These are "usually" auto resetting, however if yours are the manual type there would be a small button on the side of it sticking out that would need to be reset if it were tripped. You may also have a blown fuse or breaker tripped in your main panel. Try opening the breakers fully and then closing fully to reset. Let us know what you find.

I had the same problem and finally diagnosed it as tarnished/corroded battery connection. Happens a lot around the lead acid battery but was so nominal I didn't even notice it at first. While you are doing that look for the battery to ground connection, another place where a little corrosion goes a long way to frustration. Take you multimeter and put the red end on the positive clamp and negative clamp. If you have voltage keep going to each junction and testing both sides till you find the stoppage. Unless, of course, you do have a battery cutoff switch somewhere.
