ok guys, back at another nightmare. 2006 6.6 duramax 4500 series. 42k miles Auto. Alternator wont charge... New alternator, then new AC Delco alternator. 3 new Interstate batteries. New Bosch glow plug heater. Checked all fusible links. Have cleaned all junction blocks 2x. Swapped ECM and PCM from same identical trucks we have. Still no power being made from the ALT. Any help GREATLY appreciated... The truck has been parked since December. No lawns to cut in the winter, lol
