Dont know what happened to my previous answer,please forgive me if it shows up,together with this one.I have built well over 250 single wire alternators,most went on "A" Fords,but they show up on about anything that has a battery and a belt to run it. I can take a Delco unit and produce 6,8.12,or even 24 Volts. I have a 6 volt POSITIVE ground unit ready to go.These units have special regulators,built in,and need zero maintenance.One wire goes right to the ammeter,and no otherconnections are needed.
