Pic of RV elec system, please post
I can't find the pic of the RV elec system that has been posted here many times. If you have it would you minding posting it? (Battery doesn't want to charge, trying to noodle out the problem)

- Take you pick...here are a bunch.....LINK
- This is the one I like to post when folks need one...
Of course this one is very generic - basically to get folks familiar on what may be hooked up and what you call them...

Roy Ken - Op here...Thanks.
- Easiest way to tell is to put a multimeter across the battery terminals without shore power connected. If it is fully charged it will read 12.6-7VDC.
Then turn on shore power and this DC VOLTAGE reading should jump to 13.6VDC (or higher) depending what charge mode the converter/charger is doing...
Bothe the converter/charger and the battery cables feed the same point of the 12VDC Distribution Panel where the fuses are located...
Another simple method to tell if the battery is in the circuit is turn on the ceiling lights in the trailer without shore power hooked up. They should come one if the battery is connected to the 12VDC Distribution Panel.
common failure is having the disconnect switch opened up - blown fuse very close to the battery terminal - blown two reverse polarity fuses in the 12VDC Distribution panel - bad converter/charger unit or circuit breaker tripped when shore power is on...
If you have recently pulled the battery out you may hooked up the battery cables wrong...
I always look for the WORD 'NEG' or the SYMBOL '-' on the battery case and make sure this terminal goes directly to the trailer frame ground...

Thanks Roy
YA, I've got to break out volt meter, something goofy going on.
Plugged into 120 at home and generator won't start. Micro and A/C works. Except gen won't start. Get the rap, rap, rap of solenoid clicking, like a dead battery. Then I put battery charger directly on battery, Cheap gauge and light on charger says battery is good to go. But same as above, gen won't start. Just hear solenoid clicking. Then I start engine and rev'd up a bit to kick in alternator, 20 min later of idling gen starts no problem. I re-did some wires that didn't look so good couple years ago, maybe I missed some? I'll break out volt meter to see if I can isolate better to find problem.
