First off, thanks Nova, the info was helpful. So, because I'm a hoarder of sorts, I still have the original harness from my engine package. I checked it, and the GBCM pigtail is still there, but no module. So I got to thinking, because I'm gonna put an '04 regulator into the '05 alt., why can't I wire it like the old days and CS series alts. I'm thinking that the exciter feed from the PCM is resisted (reading 10vdc at the pin)not B+, why couldn't I just attach what was the duty cycle wire from the PCM, to the B+ post on the alt. to sense voltage load, and let the regulator do its' thing when the demand is needed(wire from the alt. pigtail, not the PCM), not just achieve a constant output, no matter what. Any thoughts?
