BINGO! Your power center charger itself will gradually
suck down your batteries. Also the LP detector as you

of my trailers. This has been discussed here many times.
It's a fairly easy job. I put mine in the toe kick area
below my kitchen cabinet right next to the power center.
It's a 1 or 2 beer job easy!
You can pull fuses one at a time and use a multi meter
set to read Amps. The meter should be capable of reading
a couple amps without frying the
meter! When you place the meter probes across the
fuse terminals (with the fuse removed) you will
see the current going to that device. I found current
going to my on board battery charger (power center)
as well as my LP detector.
Several of us here have used battery switches similar to
Amazon.com: 9001e e-Series Battery Switch Selector: Sports & Outdoors
I used the same brand but mine is just off/on.
(I didn't see the need for the 1-2-both battery modes.)
Amazon.com: 9003e e-Series Battery Switch Single Circuit ON/OFF: Sports &
Also when my trailer is at home I have it connected
to a battery tender Jr. I still shut off the battery disconnect
every time it's not in use but the battery tender stays
connected until we hitch up.
RANT MODE ON-- BATTERY DISCONNECT SWITCHES
SHOULD BE STANDARD EQUIPMENT ON ALL RVs!!!
