It is more complex than this but your 120v bus charger charges the battery bank
which supplies the 12v power to the 12v components through several 12v load
centers. Put new fully charged batteries in the bus and if the charger is bad
in a day or so you will be right back where you started. Dead batteries and no
lights. The time it takes depends on how may 12v components you use and what
their power requirements are.
Think of it like this. If you leave the lights on in your vehicle the battery
will go dead and the car will not start nor will the lights come on. Place your
newly purchased 120v powered portable charger on the battery for awhile and
walla, the vehicle starts and the lights come back on. Leave the lights on
again and you get to repeat the process.
The 120v also supplies equipment such as the convection oven, washer/ dryer,
electrical outlets, air conditioners, etc.
You would not want the 120v to get in with your 12v because that would not be
good! 120v introduced into the 12v system would likely cause the batteries to
blow up and burn the bus down.
Hope this helps you.

Teri- if your charger and batteries are toast- your 12 volt is not going to
work, either.

Subject: [WanderlodgeForum] quick question about the power problem
Hello,
Got one more question for everyone please. Why is it that nothing that
is 12v or 12v/120v both works? I understand the part about the
batteries being possibly shot, but it has been plugged into shore power
the whole time and still is. Do these items run off of the batteries
even when you are plugged into shore power? It seems to me that if you
are plugged into power everything would work.?.....Just curious to know
the answer. Any imput is greatly appreciated!
Thanks again for all your help. Robert has been having fun.
