Are you sure you got the batteries hooked up correctly?

Expert:  Randall replied 1 year ago.

Check to be sure you didn't get one cable wrong or not connected at all. If you can, attach a photo of your hookups to your post so I can see what you have.

All connection are correct it's almost like the main switch won't switch on everything worked after replacing the batteries and the battery charger is working batteries have 12.5 volts. The tv in front and back work but no lights inside and fridge won't come on. it is plug in to shore power won't work with generator either

Then you have something wired wrong...........if it was working fine before you changed them out and now it won't. Try jumping across the battery disconnect solenoid and see if you have power. And you should see about 13.7 VDC out of the inverter/charger. Attach a photo if you can so I can see the wiring and look and see if you dropped a cable down that didn't get connected. Easy to do.

Were you able to get a photo or this for me? Or were you able to get it sorted out?
