Phantom Load/Battery Issues

[danesk]

Thank you Clay. I will work on that tomorrow. Happy 4th!

I'm wracking my brain to think of anything Clay hasn't covered.

I realize you disconnected the start battery, and that should stop any "secret" use of the combiner.... unless there is any way "start assist" could still (try to) combine the start and house systems (thus a Ford or step or dump valve draw could get through)? You could always disconnect the combiner positive at the house bank to be 100% sure.

Also, although theoretically these are all "cab" draws, have you tested removing fuses on the Chinook-added fuse block at driver's left shin? Who knows what any hot taps or etc. might have been used for over the years.

Chinook-added fuse block at driver's left shin?

That was my thought. Can't remember what it powers.

[Blue~Go]

Normally the most it powers (in Concourse where it does the most things) is the following:

1) Beverage Mate heated/cooled console
2) Marker lights (and taillights)
3) Driving lights
4) Powered mirrors
5) Fancy rear view mirror

6) Always hot tap(s)
7) Ignition controlled tap

Also the ignition can be hooked to powered dump valves or powered step.

Here is a photo of the added Chinook block in a Concourse (it did less things in the Premier but same idea). Then a diagram that show both Concourse and Premier. Click to enlarge.

Many thanks to all the fine folks who posted advice for my issue!

Everything has checked out, but still have the phantom load. I now have ordered a battery disconnect switch (Blue Sea) which will solve the issue; not the solution I had in mind, but should work fine for how we use our Chinook.

Happy 4th of July!

There might also be a partial short somewhere. There are a couple of circuit breakers between the battery and the LVD that have been known to corrode over time.

Where would these circuit breakers be?

Don't know about the Destiny, but for the Concourse, it is under the LVD outside the battery compartment.

I still think that it is possible to pin point the drain/load if you systematically disconnect the cables. Electricity goes thru the wires, and you can account for it. There is no phantom, since you can visibly see all the wiring.
