2018 Jayco Hawk Battery Voltage

[Therese]

Hi all, I have a 2018 Jayco Hawk hardly ever used.
My query, one of many is the battery voltage monitor. If nothing is on fridge is on the gas , why is the discharge 0.4 . Why is it discharging?

LP leak detector, TV antenna amplifier, any monitoring devices or BMPRO systems draw power.

Factory battery disconnects usually do not disconnect everything, mostly used so slides, power jacks and awnings do not operate when traveling. And you DO need a connected battery when traveling, emergency brakes are ran off RV battery.

Install a battery disconnect or disconnect your negative battery cable if you're not using it. My Pinnacle would drain the original battery in 4-5 days just sitting there.

All the tiny electronics like ARoamer stated above have what's called parasitic draw or drain. These are the electronics on board that have a consistent draw on the battery regardless of being off. You need the battery disconnect to keep this from happening. Or disconnect the cables all together.
