FAQ:

Q: How do you install a single wire alternator?

A: Disconnect the negative battery cable at the battery. Mount the alternator to the engine. Follow the battery positive cable from the battery to where it is connected on the starter relay. Reconnect the negative battery cable to the battery.

Q: How to hook up a single wire alternator?

A: Mount the alternator to the engine. Disconnect the negative cable from the vehicle battery. Connect a 10-gauge wire from the output stud on the alternator back to the positive battery terminal. Reconnect the negative cable to the battery.

Q: How do you rebuild an alternator?

A: Taking it to the dealership? Taking it to a locally-owned repair shop? Fixing it yourself?

Q: Is there a Ford alternator one wire conversion?

A: Yep, gone. In their place goes the alternator, and that one wire going to the ammeter, now is the one wire coming from the alternator. At this point, let’s think about the ammeter. First, you can’t run to the same side, since with the 12 volt conversion, we are going to use negative ground rather than positive ground that all the old tractors used.
