It's only the interior LED lights that are connected to the master switch. The exterior LED porch light works and the bathroom light works.
This may not be any help, but I'll mention what I know about fuses and circuit breakers in our 2016 ERA 70A, which may or may not differ significantly from your ERA.
I'm aware of at least 3 sets of fuses (of varying sizes):
- Under the dash, left side, next to hood release. Probably all MB Sprinter-related. The OBD-II port is located adjacent to the fuses and hood release.
- Outside (left side) of driver's seat under a plastic panel
- Panel under rear bed on drivers side
There is at least one other fuse in ours, a glass fuse inline in the front TV's power cable. In our case, the cables were cut a bit short and stress on the plastic fuse holder eventually broke it. I'm guessing the rear TV has a similar fuse, but I could be wrong.
I don't know what fuses go to what devices. Some of the folks on here that are really good at reading the electrical diagrams may chip in with some more useful information.
There are circuit breakers on the outside (right side) of the passenger seat, and another set under the wardrobe cabinet.
Good luck resolving the lighting issue.
The battery mode solenoid is mounted under the passenger seat. This controls connecting the alternator to the coach batteries for charging, as well as the battery boost feature that allows starting the engine from the coach batteries. The passenger seat has to be removed for access to it. The factory solenoid seems to be of poor quality and various sources claim better aftermarket solenoids are available. After suffering a solenoid failure on a trip and the coach batteries not charging, we now carry a spare solenoid that we can change when we are on the road.
On an unrelated note, our ERA has a power switch above the AV system mounted behind the driver that provides power to the Over The Air (OTA) TV antenna system. A fairly common point of failure, and easy to switch off accidentally. So if OTA TV isn't working and you have a similar switch, check it. Ours has a tiny switch and equally tiny green light that glows green when the switch is in the on position.
I've found the Winnebago customer service team to be pretty helpful when I call them.
BTW, there are a few ERA-specific threads in the Class B section of the forums.
