Desperate, 12V electrical probs, Please HELP!

While boondocking last trip in our 2013 24S noticed short cabin battery life. Sure enough had boiled all the water out. Replaced batteries, and after reading here decided to upgrade to the PD 9200 series converter to solve boiling problems. Now when connected to shore power everything works great in cabin. When I unplug from shore power no 12V lights in cabin or outside, no water pump, no fridge, no TV the only things that seem to work off battery is slide out, awning, and generator will start. Figured maybe new converter was problem so I put the WFCO converter back in, and it made no difference, same problems. Have checked all fuses in power center, and they are all good. Plug it back in to shore power or start generator and everything works fine. Any suggestions would be greatly appreciated, as I am about to pull out the very few hairs I have left! Should also mention the Magnadyne is pulled out of the dash and is currently at Magnadyne repair shop for repairs, could this be the problem?

Sounds like certain 12v circuits are down. Check the breakers and use a volt meter on the fuses in question for starters.

Sounds like it, or the 12 volt resettable fuse from the battery.

This thread may help. Turbs has pics of the fuse, with the button to press. It solved that members same problem you are having.

But if he's gettin juice (when off shore power) selectively (awning, slide) and everything is working fine on shore power that tends to eliminate the converter and transfer switch... and selectively on 12v would seem to eliminate the main breaker out on the frame.

It's gotta be in the distribution panel. I would pull the box and sick a voltmeter and magnifying glass on it. Its not terribly uncommon to have a fuse give up the ghost with a hairline break you may not be able to see with the naked eye. Hopefully you've just got a loose or dirty connection. You would want to look real close for any hint of corrosion or scorching.

That would be where I would start.

Some disconnects do not kill all 12 volts. Slides, jacks and awnings etc can still work with disconnect off.

On our 2012 Solera "S", the awning, slide out, steps are wired ahead of the 12 volt battery disconnect switch. Not sure about the generator. Lights, water pump, TV, etc are wired after the disconnect switch. My unit would act as described if the switch was turned to "off". Defective disconnect switch/wiring?

Interesting. I don't think I would much care for that type of setup. Having to physically disconnect your batteries in order to power down seems to kind of defeat the purpose of having a disconnect switch in the first place. Flipping the main breaker would be about the same difference... you'll still have hot lines here and there.

At any rate... the OP could find if that's the case by metering the main 12v input at the panel. Could very be a bad disconnect then.

The line between the converter and the batteries are fused (resettable) in a couple of places.

This "general" schematic of the battery control center may help finding where to look.

I included the 2010 and 2011 Solera wiring diagrams.

Thanks to all for taking the time to offer help. I don't know what I would do without you guys. What finally fixed the problem is inside the Battery Control Center box in the stairwell there is a converter relay with a reset button the side and it was tripped. So after three days of tracing wires looking for fuses I finally looked at the diagram on the inside of the box cover and I was able to find it. It is very well hidden behind other connectors but it is there. Very small black reset button that you can not see, but if you feel for it you will find it. Thanks again.
