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.

This is not an endorsement of using this system! It is simply a statement that these things can use many different types of componants and things do not have to be complicated to get the job done.
