So what truck manufacturers are using these "smart" charging systems in a 3/4 or 1 ton?
I don't have proof, but I would say ALL of them ! I don't know who else makes Class A chassis, but the Ford F53 uses it also.
Like I said before, smart charging make a measurable difference in fuel economy. Maybe only 1/2 - 1 MPG, but it is measurable. With the Ford F53, it is easier to "leave it in" than it is to "take it out" because without the logic in the PCM, the alternator regulator would have to be changed.
Exactly
when it showed up differs between manufactures and even between models from the same manufacturer.
