Dead battery no power even hooked up to shore power

Just bought this 03 jayco. Everything worked till the battery died now I have no fridge no water and no heat or lights. I'm hooked up to shore power still only wall sockets.

Sounds like you have a blown fuse in the converter. My guess would be a 30 amp fuse. The other cause may be a bad/blown converter. Need to know the make & model of your converter for a more detailed troubleshooting answer.

As said above. The converter has a set of fuses (some have 2 others have 3) that blow if the battery is connected reverse. In most cases the black battery wire is positive (brake wire is blue) and white is negative. But not always.

On my 2010 Jayco 23B the battery connections are white/black but inside they used orange, black, and red for positive. You need to follow the wires from the battery to the the converter to be sure which wire goes to which terminal. Newer jaycos with LifePO4 batteries used the more traditional black (negative) red (positive) colors.

Find your converter then Google the model number to find a manual for it. The manual will have specific troubleshooting instructions for that converter. If you're plugged in and not getting any 12V power, the converter isn't putting out power. There are a variety of possible causes, including the fuses mentioned above.

Starting at the battery, look for an inline fuse holder that looks like this one:

If you find one, test the fuse inside. A green colored fuse is 30 amps, and if blown will prevent the converter from charging your battery.
