Phantom loads
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, 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.
