Question House Battery can only be turned on with engine running.

[MKB]

2021 Winnebago Travato 59G house battery switch can only be turned on when engine is running. Also battery switch goes off as soon as engine is stopped

House battery is dead or there is a problem with the solenoid that powers(charges) the house battery when the vehicle is started.

Welcome to RVforums. I agree with Thelooks. If you have a volt meter see what the voltage is at the battery without the engine running. If battery voltage is down have the battery tested. If the battery tests good you could bypass the battery switch and see what happens. I tend to believe bad battery, switch.

It is getting 12 volts from the alternator. Something is isolating it from the chassis or house battery. Is this a new problem? If so, you are hunting for a fuse. Good luck, they hide those rascals everywhere. It will be the last place you look.
