Which switch are you referring to as "disconnect switch"?
Big red switch with a picture of a battery on it. By the sliding door in 2014s, under the sofa in my 2012.
The electrical system is the biggest mystery and I don't think it's well explained in the manuals.
Not helped by the lack of a wiring schematic. But then again, if they included a wiring schematic, they'd have to follow it, rather than making things up as they go along. Even within a model year, you'll find exceptions on individual Interstates, where the installer wasn't paying attention to what he was doing.
There seems to be a lot of parasitic drain I have to resolve.
Some of it can be learned by experimentation. But in general, any time you have anything
turned on, there is a drain, so the only way to minimize parasitic drains is to consistently turn off everything.
On some Interstates, the battery disconnect also disconnects power to the propane solenoid valve. On mine it doesn't. Easy way to find out is an experiment. Light a stove burner. Then turn off the house battery power at the main disconnect. Wait a few minutes. If the stove burner stays lit, then shutting off the main disconnect doesn't
kill power to the propane solenoid. Since the solenoid, all by itself, draws about 0.75 amps, that's a whopping 18 amp/hours per day of parasitic drain!
Same sort of thing for the antenna amplifier. On mine, the battery disconnect doesn't shut off power to the antenna amp. Again a simple experiment. With the main disconnect turned off, press the button for the amplifier. If it lights up, the amplifier isn't
controlled by the disconnect and will have to be turned off separately when you're done with it.
I haven't systematically tested everything
to see what's shut off by the battery disconnect and what's not; I haven't tried the MaxxFan or bathroom exhaust with the disconnect switched off, for example, or the motor for reclining the sofa.
When I store mine, I have a simple checklist.
1 - Turn off the propane solenoid.
2 - Turn off the antenna amplifier.
3 - Flip all the 120vAC breakers to "off."
4 - Turn off the inverter/charger.
5 - Turn off the battery disconnect.
That takes care of most parasitic draws. Whatever is left is low enough for the 50-watt solar panel to keep up.
Since I have an alarm system that still has to be powered even when the unit is stored, I don't pull the chassis battery disconnect located by the accelerator pedal. That means I have to start the engine about once a week to charge the chassis battery, while there's still enough juice in the chassis battery to
start the engine!
Since the generator also has to be exercised periodically, I run the generator the same time I run the engine while the unit is stored.
