The following is (I think) what you need. Using a Delco 10SI alternator. To wire a Delco 10SI First remove the generator and both wires going to it from the regulator. Looking at the regulator there will be either one or two wires remaining. If two, one will be from a terminal with BAT on it. The other will have an L on it. The BAT terminal connects to the amp gauge output terminal. It is going to be replaced, so take it off. The L terminal will connect to the Light switch through a fuse. It will be shortened and connected to the amp meter where the BAT wire was hooked. If the regulator only has a BAT connection, it will be connected to the Amp gauge output terminal. 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 a wire from #1 spade terminal on the Delco to the ignition (before the ballast resistor, if it has one, with the band on the diode toward the alternator. The diode can be placed anywhere as long as it is not going to rub on metal, and should be taped up or protected with big shrink tubing. The #2 Alt terminal should be connected with a short 12ga.wire to the Big output terminal on the alt. A new heavy wire from that big terminal will now go to the amp meter output side mentioned above (must be 10 gauge). The amp meter leads must be swapped so it reads charge correctly with the battery polarity changed. (all leads switched side to side. 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. The ignition coil should be reversed so the + terminal goes to the points, and the - terminal gets voltage. No other changes are needed. Jim
