ORIGINAL: Mode One
My first set-up simply used a duplex 120 volt AC recepticle and plugs. The starter went to the plug marked starter and the glow driver went to the other recepticle. This system worked great all the time I used it. I used the ground prong as the method of maintaining and assuring polarity. This system was in use only back in the times when people had common sense and the owner was the only one who used the system and understood the dangers of plugging a 12 volt, DC starter into a 120 volt AC recepticle.
Since I've managed to plug my glow lead into one of the 12v spots on my power panel (resulting in an instant death to the plug) I guess I'd better not use your method. I don't want to have to buy a new starter! [X(] However, building on your idea, there are plenty of other types of recepticles that could be used on the flight box that wouldn't expose the starter to death by 110v from people like me.
