Alternator Questions
I am in the process of installing a Cummins 12 valve engine into a 1996 Ford Shuttle bus that I use as a car hauler. I need to fab alternator brackets and rewire so I have to choose an alternator. I have 3 choices: Dodge/Cummins Denso 120 amp, Ford 130 amp 3G, and a Leece-Neville 165 amp unit. Currently I have the Ford 3G on the 460 in the bus since the L-N had problems (turned out to be in improperly wired regulator but after installing a new internal regulator, the alternator is now in fine shape. The 3G probably puts out the most amps at low speeds which is a plus for the rear mounted A/C unit. I realize the Leece-Neville was installed in the ambulance-ready models so does that indicate their reliability and output?

The Leece-Neville unit was Ford's optional high output unit in the old days. I think it or the 3G would serve your needs well. So I would look at both and see which is easier to physically mount.

I am using the 130amp 3G alternator on the 460 currently in the bus and I guess it keeps up pretty well even with the condensor with all 3 fans running. Am I correct in saying that it seems the L-N alternator is build heavier than the 3G?
