My truck runs rich when the alternator is plugged in. When plugged in I get 14.5v at the battery and the truck runs rich. 10% CO and HC ppm to be exact. It runs good but not as crisp as it should. When I unplug the alternator field fuse and/or unplug the alternator connections it runs much better and you can't see even a hint of exhaust.
Any ideas other than "you have a bad alternator"?
