12volt issue rock wood 233s

[Billyb]

Hello

I'm having an issue with the 12volt system in my trailer. Just put a new battery in and still nothing no lights etc. Shore power everything works fine???

Do you have a battery disconnect switch? It is usually a silver knob very near your electrical control panel. You pull it out to engage the battery. If that's OK, then you probably have a blown fuse or a tripped in line breaker which is usually wired in very near the battery.

Have you seen this someplace?

If so you might try pressing the little black button.
