Hello everyone, Happy New Year!
I purchased a new chrome high output alternator for my 2003 Silverado 4.8 to help with my custom stereo and after installing it a "Service Break Booster " came one the dash display when driving.I have had no problems before installing the new alternator so i put the old factory one back on and everything works fine with no errors. I took the new alternator to Autozone and had it tested and it passed with no problems. Anyone have any ideas of what is causing this when putting the high out alternator on and how I can correct it?
