I don't have a negative thoughts about the Bosch. I went with Valeo for a couple of reasons. One, I have a SRT-6 and it takes an 8 rib pulley. I looked at the alternators with a 6 rib pulley. The back spacing seemed different. (Bosch, Carquest, etc.) No clue if they'd work or not with a pulley swap. My original was Valeo. Valeo alternators could be found with an 8 rib pulley. The original was Valeo. I got the Valeo with an 8 rib pulley.

Check the battery. Your bad alternator may have killed it.
