Low DC Voltage in Coach

Living in our coach and desperate for a fix. 12 side not working and 120 side working. I have reset all the breakers that I can find. Chassis battery is working fine, coach batteries aren't charging either with engine running or connected to shore power. Batteries are new. Please respond ASAP if possible.

First check voltage on all batteries.

Next check your disconnect switches.

Check voltage at converter.

There are large fuses between batteries and coach so verify voltage measured at battery same as that at converter.

Engine may not charge cabin batteries so if you can get a battery charger connect it to cabin batteries if needed.

Welcome to the forum.

Did you drop a wire when you installed new batteries?

Post your rv model and yr.

Time to find your converter, panel, etc. In a pinch grab a portable charger to keep things going.

From his info

RV Manufacturer NationalRV Mode lSeabreeze 2006RV Length36.5' If the engine and shoreline are not charging then something common such as a dropped wire when installing batteries is very common.
