I'm thinking about putting a 12 volt stand alone charging system and battery in my M923 to power standard automotive things. Has anyone ever done this? I don't see where it would be very hard to do. The toughest part would be mounting the alternator on the engine somewhere. The wiring, gauge, and warning light would be easy as would a battery because I only run 2 so a third stand alone is no problem. I think I may be able to do it for less or about the same as a DC converter would cost. What are your thoughts on this?
