Dead chassis battery

[kayo]

This is drivingme nuts. Even with a manual battery disconnect, my chassis battery will completely drain. I am guessing that it has something to do with the screwed up Intellitech system, but it is way above my paygrade to find where the unintended phantom ground is.
Any help would be appreciated

I feel your pain...but, it may not be a phantom ground...could be a parasitic load.

Is the "manual disconnect" you mention, the one that Damon installed...or a REAL manual disconnect switch?

My Damon is in OEM set-up for the house electrical - except for this big fat manual disconnect switch on the battery terminal:



I found that the original (solenoid operated) power disconnect switch would still let some power flow (just the solenoid itself needs power).

By putting the switch on the ground terminal, I was able to easily leave a solar charger connected to the battery bank, but the mystery load stopped. And, my "emergency" action for any smoke in the coach includes pulling the key on this switch upon exit (battery bank is under the entryway steps).

Good luck!
