Good question. THe one wire Delco is equipped with a regulator that is self exciting. It has two problems, one is that it needs to be operated at 3/4 throttle or more to begin making volts. (it continues after that even at idle) The second is that they tend to run down the battery between uses. They kinda leak current when not being used. The easiest way to use the multi wire system with a mag is simple. Use a NAPA oil pressure switch that turns on with pressure of 5psi, and is open when no pressure is on it. T this switch into the oil pressure port and run a Hot wire from the starter sw. to the pressure sw, then from the pressure sw to the #1 terminal on the alternator (The standard SI-10 unit) This needs no diode, no idiot light or any thing else. The #2 terminal hooks as shown to the Big terminal on the alternator (just a short wire). JimN
