Alternator rating - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Looking for a documented source for our OEM alternator (LS/SS), either from GM or AC Delco/Boshe/etc that lists or discusses both idle and max amperage ratings. The only items I am seem to find are "it runs electrical stuff", "12-15.5v", "controlled by the ECM", tons of threads like this one with claims of 150 Amps and parts stores just saying "OEM replacement". Alas yes, I performed a search here and none of the 40 threads I read through showed any promise either. I did trip over a few "GM Engineer sent me this" posts that discuss how the ECM controls the variable voltage regulations, but again nothing there discussed variable to max amperage ratings common with all after market models. Even the Owners Manual does not list these dark secrets!

According to my build sheet, my 2010 Camaro has option KG4-Alternator, 150 Amps.

150 Amp would be max output. Minimum/idle output is anyone's guess, though I would suspect somewhere in the 100-110A range.

Very much appreciated, also reminds me to order my build sheet!
