DC Power Issue

[StevoDevo]

Hi Guys,

I've got a Four Winds Chateau Citation 23A that is having issues with the DC power and I need some help troubleshooting it!!

Here's the problem - when I'm on Shore Power, or Generator everything internally runs great (lights, water pump, etc) but as soon as I disconnect Shore Power, or turn off the Generator then there is no power inside the RV.

The House Battery is fully charged and I've tested it and made sure it's working great (it's only 3 months old). The House Battery seems to come into RV via the Red Cable (from the floor) in the picture below:



It connects up to the switch that I marked with an arrow and when I check there is 12.6 v on both sides of that switch. I'm using the copper ground cable pictured as my ground for testing.

The red cable goes from the switch into the breaker box pictured below:



I get the same voltage when testing at the right and white cables. I also tested by grounding the tester on the big white cable and then testing on the silver screw heads next to each fuse and got 12.6v there too.

So I'm not sure why there is no power inside the RV.

Does anyone have any ideas? I'm not good with electrical, so if my testing is on the wrong cables, please let me know what I should be testing!!

Thanks so much!
Steve

I double posted by mistake and can't work out how to delete this one! The one in the Maintenance Forum is the one I wanted to keep!
