Re: 1982 Regal 245xl
I am going to take a guess on the battery wiring.<br />I had a 1991 regal 290 with twin 5.7L. It had three batteries with simple on-off switches. Each engine had it's own starting battery and the house<br />(cabin lights, fridge, etc) had a seperate battery. Sounds like you have the same set-up, only you have the option to switch which battery is used for each system (engine1, engine2, house).<br /> I looked at the pics of the large lighted buttons and am totally stumped, maybe Charlie or someone else might have an idea.
