Got some feedback with the possible alternator issue....
Pulled codes 622 and 1594. Battery tested good. Charging system read High Voltage (no load 17.66v/128a loaded 17.25v/86.1a). Belts, connections, and grounds look good....
So when the test report "recommends" Regulator Service, what does that mean? doesn't the ECM control the regulator functions?
Do I need to test the Alt or just replace it?
Thanks,
Lance
