Greyhawk Battery Disconnect

Ok, so I just put my rig into my covered storage spot.

I clicked the disconnect button and verified that my interior lights and what not didn't work.

I noticed the dash A/V - Head Unit still had power. I pushed the volume knob to shut off the radio (but I can't tell if that just muted it) and than I clicked the display off option to shut the screen off. Seems like even w/ those two steps I'm going to have a parasitic draw on the chassis battery.

The power step still came out and back in. Looks like that worked irregardless of the disconnect switch. I was kind of hoping it didn't. And my propane detector still had a green light on it. Maybe I didn't wait long enough for it to dim, but it seems like that was still on.

Am I missing something?

I would bet steps / safety devices work regardless of the disconnect. Our radio does go out when we push the disconnect.

I keep my rig in storage w/ no power. On my Winnie the disconnect really disconnected EVERYTHING.

How long can I go w/ these little things still 'live' before I have a problem?

X-2 since you could have people in the back even though you are not using the lights, fridge etc.

On my 2012 31DS, the disconnect switch does turn off the LP detector and the Clarion entertainment unit. The stairs still work, but they should have no draw unless actually extending or retracting. When the disconnect is activated, I measure only a few milliamps current draw at the battery.

Angry When is a disconnect not a disconnect

What good is a battery disconnect that still allows parasitic draws???

I know the disconnect does not impact the radio on mine, it continues to run and I have to hold the power button down to turn it all the way off. But I suspect the radio runs of the Ford battery instead of the house?

My stairs also continue to deploy after the switch is thrown, I am not sure about the LP sensor? Is there any chance the stairs are run off the Ford battery as part of the safety feature which causes them to retract once the vehicle is running?

As a shiftworker it is not unusual for me to go 3-4 weeks between trips so even small draws like the propane sensor are enough to significantly deplete the battery. If these things do continue to draw I will have to consider adding a secondary disconnect to properly protect the battery

I must not have had enough patience or maybe the capacitors in everything were all nice and juiced up.

I went back after work and verified my radio DID turn off w/ the disconnect switch. And the propane detector light DID go out. After a bit.

I agree, the only thing that should draw on the battery during storage would be the propane detector, provided the audio/navi is turned "off". For a while I was disconnecting my chassis battery during long term (winter) storage. I still had to charge the battery in the spring.

I think every one of these units is wired differently. Mine does not turn off with the disconnect and is wired to the house battery. Shares a circuit with the stairs and the Bauer lock.
