A 10 gauge wire goes from the big output stud terminal to the load side of the amp gauge. From the other side of the amp gauge a 10 gauge wire should go to a 40 amp fuse link. From the fuse link a 10 gauge wire goes to the battery connection on the starter, or the battery side of the heavy current starter switch. (this leads directly to the battery positive post) From the #2 spade terminal on the edge of the alt, a 6" long 14 gauge wire is connected to the output stud. (this wire controls output voltage by sampling it at the source. From the #1 spade terminal, a 14 gauge wire attaches to one of three things: a diode with the marked end toward the alternator, or a 10 ohm 10 watt resistor, or a lightbulb type side marker lamp. Using one of these options prevents the alternator from keeping the engine running. The diod, resistor, or lamp other terminal is then connected to the ignition so that it gets 12v power only when the ignition is on. (if a ignition resistor is used, it should be on the ignition switch side of that resistor, not the coil side.) If the diode is chosen, it can be found in an old alternator, or from an on line source. it should be able to handle 4 amps, with a 250 PIV rating. Common commodity device. If a marker lamp is chosen make sure that it is not grounded, the connections are through it, not to ground. Good luck, it is not hard. Jim
