Converting my old Ford from a generator to alternator. A bit confused on wiring. Alternator is Ford Motorcraft with attached regulator. Alternator has a battery plug with two wires also has a STA plug . The attached regulator has an A S I plug. I connect the batt wire to the positive side of my starter solenoid. The STA on alternator I attached to the S plug of attached regulator. Where does the A wire and the I wire on the attached regulator go and how does this hook in to the wires on my old generator regulator which is marked A F B.
first is to determine which alternaor version you have, 2G,3G,4G or 6G
2G Solid back end, 2 plugs, one is BBS other is ASI. You probablly do not have this one. B $B go to battery. S goes to S on regulator plug. I goes to ingition, thru light. A is battery
3G 3 castings, the thin one in the back may be black, and there are 2 plugs, one on regulator is ASI, another one not marked is on the rectifier , is a small pin sticking out. The little wire terminal goes to the S. A goes to nattery. I goes to ingition thru lamp.
4G short fat one, with stamped metal end cover. A goes to battery. I goes to ingition, thru lamp.
6G looks a lot like 3G except regulator is under cover in back, A goes to battery, I goes to ingition thru lamp.
You probablly have a 3G. Look at the regulator, if it says SE, then no connection is needed. Self exciting 3G regualtors are available, and make this a lot easier, just connect to battery.
Good luck
