Go back and read your post and then try posting it again so it makes sense:
Quote:
with out shore power, most nothing else 12volt works
|
Quote:
I just can run things like lights , furnace, fridge light, water pump, like boon docking.
|
That's the way its supposed to work.
Quote:
with out shore power , nothing working
|
completely contradicts what you just said.

Make sure your use/store switch is in the use position, check your "new" battery with a volt meter, should read more than 12volts DC.

If you have a USE/STORE switch turn it to USE so that battery power gets to the 12 volt circuits.

I had the same symptoms.
Turned out to be a faulty (or dirty/corroded) Use/Store solenoid.
In order to allow my coach to function properly for now, I over-rode the solenoid by connecting the positives together at the solenoid. Thus I currently do not have a functioning Use/Store switch, but the electrical system functions correctly.
I've ordered a new solenoid from Amazon for $35 which matches the Thor OEM.
