I was talking to Harvey Lawrence and he told me there was always a
phantom electrical load in our coaches. While working on my step valve,
I noticed that one side was hot. I called Bennie at Bluebird and he
said that those units were supposed to be that way in the early coaches
and that they changed design later on. Thus, if someone has a dead
battery, this maybe an area that consumes our electric current.I don't
know if that could be controlled with the electronic master switch or
the 12 volt kill switch. Ernie-83pt40- hot inoperative step

Ernie, Phantoms are nearly always present and they do
drain the batteries in time. One of the most useful is
the one that keeps the clock set so you don't have to
continue reseting.
Normally they will bypass the Masteror Kill switch.
To determine if you have one, lift the positive terminal
then put an ampmeter in series with the positive post and
the cable clamp. Start on a high scale reducing to a lower
scale to see what current drain the battery sees when the
Master is off.
The only time this would be of concern is when the coach is
unplugged from shore power or the genset not run for an
extended time.
When you get the smart charger operating you wont have to
unplug the chargers to prevent cooking and worry about the
batteries going dead.
