I upgraded in the beginning of this project, because I needed a custom pulley setup anyways. And I did know that I will run electric fans.So you're upgrading to a 3g?
So the first alternator was working 2000km... I used an alternator with Ford part number F3DZ-10346-B, which is a 3G alternator, but with a serpentine belt pulley. The pulley needs to be swaped when you want to keep the V belt.
I did! the motor trend article states, it is unimportant which way it is wired up. It explains that the idiot light or resistor is needed for GM units not the Ford units.Hopefully you can find some answers through one of these links.....
So I will buy another alternator and hope that it will last longer, when I leave the resistor away.
