To wire a Delco 10SI (or Hitachi alternator from a mid 1980s Nissan PU), the following is the method to make it work for a long long time: A diode, or a marker lamp bulb, or a 10 ohm resistor is the only other thing needed, Use insulated spade terminals for the small connections, or put shrink tubing over them to keep them separate. The diode, Radio shack part #276-1661, or bulb, or resistor, goes in series with the wire from #1 spade terminal on the Delco (or the L terminal on the Hitachi) to the ignition (before the ballast resistor if it has one), with the band on the diode toward the alternator. The #2 terminal (S terminal on Hitachi) should be connected with a short 12ga.wire to the Big output terminal on the alt. The wire going to the amp meter load side (not the side connected to the starter relay) should be 10 gauge. The battery must be reversed to negative ground. If not the smoke will be let out of the alternator as soon as it is hooked up. Jim

They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
