Several times over the past week, I wasn't able to start the motorhome by inserting the key and turning it on. Thinking it might be the chassis battery (it's less than 3 months old) I used the switch that combines the house and chassis batteries. That worked so I went out and checked the chassis battery. It was fully charged at 12.5V.
After it was running I turned it off and it restarted normally. The next day, the same thing. Insert key and nothing. No lights. We always keep the salesman switches turned off and usually when I insert the ignition key it turns them on. This time that didn't happen. At least not the chassis side. However with key in ignition I pressed the combiner switch and the dash lit up and everything was fine. I wasn't attempting to start the engine with the switch pushed in. All I did was press the switch with the key in the ignition and everything lit up. The engine started fine. Then I turned the engine off and restarted it normally.
I'm thinking either the combiner switch or the BCC has an issue. A friend suggested the starter motor but that just doesn't make sense. It starts fine when the dash lights up and there is no hesitancy when starting it. The coach has a history on the BCC so maybe it's failing again.
Any ideas.
