No 12V???
What do the batteries read for voltage?
Is there power across the self-resetting circuit breakers?



No 120V?????
Is there 120V power at the pole?
Is there 120V power at the breakers

Jerry,

First, welcome to the forum!

We need a little more info to help. Are you connected to shore power or battery only? What year and model is your rig? Is the lack of power on the ac or dc side?

Define good- what voltage measured with a VOM? Hopefully the RV wasn't left in storage without disconnection the battery at the negative or positive pole.

The Master Switch (I assume you are referring to the one in the convenience center) has confusing labels. Is the Red Key in the position where it can not be removed?

What year and model Montana do you have? What changes have been made recently (new batteries, etc)? Is the the Propane Detector beeping? What doesn't work on 12V (jacks, slides, hydraulic levelers, interior lights, etc.)?

I have to ask. Are you sure you connected the battery with correct polarity?

6 weeks is enough to drain a battery even with the disconnect switch in the disconnect position due to some parasitic loads that do not go thru that switch.

Jerry, Turning the off the red key in your convince center does NOT turn everything off in your RV. As others have said, there are parasitic draws in the RV. You need a disconnect switch on your negative side of your battery cable, at the battery, to fully disconnect all power. I would also recommend a trickle charger as well. It sounds like you need another new battery, sorry to say. Once your battery drains fully dead, itís toast. Manufacturers recommend no more that a 50% draw down unless you have a lithium battery. Take your battery to have it load tested first. Itís probably toast. Do the battery disconnect switch and a new battery, you should be good to go. Make sure to disconnect the battery switch when you put it in storage. Good luck

Since you haven't given any useful info I will make some guesses based on experience and tell you what you don't want to hear.
You say battery, that tells me you have a single 12V battery. Most likely NOT a deep cycle. If the initials CCA or MCA or the word CRANK is anywhere on the battery it's the wrong battery. If you don't want the battery to power anything when in storage you have to remove the battery cables. The master disconnect by law must still power a few things. Your battery is most likely dead and even if you recharge it it will not last long now.
