Dave,
I'm not an engineer, and I didn't stay at a Holiday Inn last
night (though I probably should have) but there is a potential
problem shutting of the power to an alternator with regard to diodes and such.
I worked on a guy's race car with alternator and was
shocked, literally, because he had the wrong switch.
This link, by no means an endorsement, addresses the
alternator issue. Maybe you can understand it better than I.
