NST Pulley Set Alternator Issue

[shinlee]

with the car on, normal output should be 13.7 to 14.5

with the car off, the battery should be about 12.5

I used to manage an Autozone, and I've done god knows how many alternator checks. If you're getting 14.1 then you should be fine. It sounds to me like there may be an issue in the wires, something not connected properly or something of that sort. A loose (incredibly loose) belt will cause it to not charge properly, but just pull on the belt while it's off, and if there's a lot of play, either tighten it up or replace it.
