Electrical Problem

2019 Montana 3120RL, Anniversary Edition, and love it.
[
Brought the 5er out of winter storage. Installed the 2 12 volt fully charged batteries, joined using parallel method. No power to the power panel??
Does this unit have an Kill switch between the batteries and the power panel?
I have searched for one for the last hour. I know this Forum has a lot of electrical experts and I most definitely need your assistance.
Regards Chukar

No expert here but look in the wet bay, drivers side "basement door". Should see battery disconnect switch. Point of red key should point to on.

I personally think it should be called a "battery switch" with On/Off. Seems if "battery disconnect" is On the batteries would be disconnected...

Also make sure you connected the batteries properly and did not get them reversed and blow the reverse polarity fuse.

Just to clarify, which/what "power panel" are you referring to?

Is it the 12V fuse panel?
OR
the 120V circuit breakers?
OR
the Level Up display panel?

The red disconnect switch in the convenience center(wet bay) needs to be in the position where it can't be removed.

The reverse polarity fuses in the converter are blown if the batteries were connected backwards for just a split second. The 12V goes from the batteries, through the disconnect switch to the converter. If the fuses are blown then there will not be 12V to the 12V fuse panel (and consequently lights and all them other 12V devices).

I call it in public a battery converter isolator.

Just to be sure-you said connected in parallel - positive to positive and negative to negative. DO NOT GO POSITIVE TO NEGATIVE FROM ONE BATTERY TO THE OTHER! That would give you 24V.
