4.1 amp parasitic draw - 2020 Ford V-10 Thor Outlaw

[spotrot]

Upon further investigation, the condition is worse than I first saw.

1.5 +/- amp draw from the G7 Module & interior fuse panel circuit
0.8 amp draw from another circuit (starts at 0.3 and then goes up)
1.8 amp from the inverter (starts at 3.0 and then goes down)

Total: 4.1 amps with nothing turned on.

The first two circuits can be turned off by the master switch but the inverter stays continues to draw even when the master switch is off.

No big deal when plugged into shore power but really cuts down on battery when dry camping.

Anyone have experience with this RV or solving this?

Thanks,

John

Thank you all for the input.

I can check step, LP detector & stereo to see what they draw. (I guess it would be very low)

Good to check TV antenna amplifier, it's easy to forget.

Even alternators draw a tiny bit but that's off the chassis battery.

I've designed battery powered electronic devices - it seems a truly poor design if the inverter draws over an amp when off.

You're stereo probably pulls some power even when off. TV antenna amplifier might be on and pulling some power. The control board in a gas refrigerator uses some power all the time. LP leak detector and CO detectors use some power.
Doesn't the inverter have an "off" switch? If not, you could install one as suggested in the battery cable. It really should have at least a fuse in the positive battery cable. Replacing it with a circuit breaker would make it easier to turn on and off.

With latching relays the control can be remote.

Put a Blue Seas switch on the inverter. You might also be able to switch some of the first 2.

Step, LP detector and inverter are a some items that draw all the time.
