This tech will allow you to upgrade your 3 wire original alternator to a one wire on your Chevy.This will eliminate the mechanical voltage regulator that can stick and drain your battery.It will work on just about any GM vehicle that already has an alternator.

If you have a 1 wire alternator, did you know that most auto parts stores don't stock parts for these? These alternators use a self-energizing voltage regulator.Might be a good idea to get one and keep it around in case you ever need to do a conversion, break down while on a trip, or find out your 1 wire alternator is sold out or out of stock for some other reason.This way you can buy the cheaper 3 wire alternator, which can be found almost anywhere, and do the conversion roadside. They are relatively cheap.Average cost is $6-$8 bucks.

The parts needed to convert a 3 wire Delco alternator into a 1 wire alternator are shown in the following table.I recommend using 10 gauge wire to go from the back of the alternator to the battery at minimum.
