12 volt only half works

[TSimpson]

I have a 96 nomad. First off the battery is new and charged and the converter is brand new and is charging the battery. I have 8 circuits on the 12v system. 1-5 run lights, water pump and vents and the last 3 radio, propane detector and 12v outlet. The problem is 1-5 will only work when on shore power and not on battery. What am I missing?

I agree with you!

The other 1/2 may be on an Inverter. Find it and turn it on.
