12v Lighter Sockets

[rlrich]

2006 SeaBreeze 1321 F53 chassis. I've got a little 15in 12v TV that I like to use when it's not necessary to run the genny. We use the 12v lighter plug under the dash on the passenger side. Is that plug drawing power from the house or chassis battery?

Given its location under the dash and that I've never seen a lighter plug powered by the house batteries, I'd say it's the chassis battery. Can you turn "off" the chassis battery to check? I have a chassis battery disconnect switch inside the MH. Or, you could remove one of the chassis battery cables to prove or disprove it. I would do the negative cable to avoid any arcing.

You have a 12 volt outlet at the passenger work station, plug the TV into that, turn it on then push the disconnect switch at the stairwell . The disconnect switch only shuts down the house battery.

Thanks for the replies. Plugged in tv, hit disconnect switch and tv stayed on so it's hooked up to the chassis battery. I was hoping the passenger side socket was on house battery and the driver side on chassis but I guess not.

Next question, if you choose to use those 12v outlets does the converter keep the chassis battery charged when you do start the generator? That’s seems to be the case with my 02 Breeze.

Yes TC, my 06 Sea Breeze does charge the chassis battery with the generator running or on shore power. Just as the alternator charges the house batteries with the engine running.
