So far so good. Drove around for an hour early this morning with everything turned on (including the rear defroster) with my OBD2 HUD and the re-man Bosch ran like a champ. Voltage was 14.5 at start-up 14.1 to 14.3V warmed-up. Loving the 130A Bosch. Wished I switched out the 120A Valeo years earlier.

I have the stock alternator on my 03 don’t see any issues.
You might have a issue with your old alternator or electrical system
