Alright, I am really stumped here. I will try and be as thorough as possible here. I am having battery power problems on my 2013 2715.
- I have no (absolulely none) power to the coach from my batteries. no light, no radio no water pump, I cant even see the levels of my black / gray tanks. but I can prime and start my generator, and my solar is charging and reading the level of the battery.
- when running my generator or plugged into shore power everything works.
- I started troubleshooting by ensuring both my batteries were fully charged.
- I have 12 VDC at the input lug of my battery disconnect switch with the switch in the off position. When I turn the switch to the on position volts drop to 1 VDC both in and out. So to eliminate the switch I disconnected it and I have 12 VDC coming from the battery, but as soon as I connect it directly to the lug going to the fuse box voltage drops to 1 VDC.
I am leaning in the direction that I have a ground in, or my inverter is not working properly.
Help PLEASE! I am supposed to go out dry camping Wednesday.
Yes, all wires are tight. It is not as weird as I originally thought about the genset, as I was tracing out wires I found that my start circuit for the genset is hard wired straight to the battery.
Have you checked the converter. Should be Maxie Fuses into and out of to protect it. Converter takes120 volt and turns to 12volt. Inverter takes 12volt and makes 120volt. do you have a test meter to check with?

Are you sure your generator starts from this same battery?
If it does, I would agree the battery is ok.
If it does not, then I would say you have a bad battery.
It sounds like you checked static voltage, which could read OK but as soon as you put any load on it, it goes to 1v.
Battery voltage has to be tested with a load. Static voltage will have you running in circles.
Do you have any way to put a stand alone battery charger (at least 10 amp) on it and see if things work?
It will eliminate guessing about a bad ground or poor connection that you seem to be leaning towards as it will be supplying the current directly from the battery posts.
Can you unhook the supply wires to your inverter to see if it is the culprit?
If you are certain the battery is OK under load, you have a HUGE draw somewhere.

I did check the converter. with shore power on the converter is putting out 13.4 VDC just as it is supposed to.
Yes I am sure it is the same battery that starts the genset, its the only batteries I have on the unit.
I did disconnect the batteries and charged them separately, I have a high confidence factor that the batteries are good. I even took them out of parallel and tried to run the coach on each battery individually with no luck.
The frustrating part here is that the TH never moved. My son is home for Xmas and was staying in it. Everything was working. My wife in an attempt to save electricity unplugged it from shore power, and my son went to bed on battery, lights worked and even the heater, but the batteries died in the middle of the night, so after recharging the batteries, I have this problem.
I don't understand how an opened circuit breaker or blown fuse would drop good battery voltage to 1v when he hooks the battery up? (Via the cutoff switch or direct connection)

Often common for owners reinstalling battery, to accidentally cross the wires and tripping resettable breaker.
it's almost always tucked up inside the trailer's A-frame.
It has a tiny black reset button.

Two things though. The problem occurred with the batteries installed, so no crossing of wires, and why would I have 12VDC at the input to my battery cutout switch.
Most converters have renewable fuses in the case protecting the battery feed to converter from the batteries. Find the converter and these fuses, + or - is open. The 12 volt supply is working but the battery feed to the bus is not.
I did see the fuse on the converter. I could not get it out and feared I would break it. Can I measure resistants across it with it in or does it have to be removed?
So after continued troubleshooting I was at my wits ends. So I started to to just flip breakers and reseat fuses. After doing all of them, still no power. So I went into the genset and flipped the main breaker there. And the lights came on in the TH. I turned the breaker back on and started the generator. It took the load and I shut the gen down and the lights stayed on.
I don't quite understand it but somehow that breaker tripped and shut down battery power but still allowed the genset to power the TH.
Anyways, I'm headed to Glamis in the morning! Thanks for the support.
