First time posting on the forum from which I've learned tons in the year and a half we've owned our 2007 Winnebago Journey 34H with 350 Cat.
I'm experiencing an intermittent full loss of all 12v chassis power to the unit. Either I haven't any power to even display anything when turning on the ignition and no electric power to driver's seat and headlights or we have power and am able to start it then put it in gear and drive a few yards to then have it completely shut down the engine and all 12v power.
Troubleshooting I note that when no power, I have no voltage readings at either side of the first bus fuse after the battery. All battery terminals have been cleaned as well as the ground to chassis. The batteries have been load tested and are in good shape and reading 13.4 volts.
I'm thinking I have something heating up pretty quick and shutting everything down. I'll then have power the next morning!
Looking for some insight on where to explore further this issue.
Thanking you in advance.
