3G

The 3g is Ford’s most popular alternator for 91-2003. Some vehicles are equipped with the 3g even later than that. You know you have a 3g if you can see the entire gray or white voltage regulator on the back of the alternator. The regulator is what you had to unplug the wires from. There is no visible cooling fan on the 3g. It comes in 95 and 130 amp versions but takes the same rebuild kit.

 

Kit contains new brush holder/ voltage regulator assembly. A new slip ring, new bearings. New pulley nut and lock washer.
