I have 1994 Winnebago Vectra Diesel Pusher and I'm having trouble with the lights not working off the coach batteries.
I can get all appliances and lights to work when I'm plugged in, but not when it's unplugged. All batteries are hooked up correctly and have ample volts.
I don't know if the converter has something to do with this or not. The converter is in a bad place to get to, so all I can see is the back and side.
I should also add that when I'm plugged in to shore power the batteries are not being charged.
I have had this problem for a while now and I'm getting tired of putting in batteries every year.
