Hey car audio peeps! I just bought a High Output alternator for my Matrix:

03 - 08 TOYOTA MATRIX HIGH OUTPUT 165 AMP ALTERNATOR!! - eBay (item 160582681607 end time Jul-02-11 06:59:28 PDT)

And I noticed that when the car idles, all of the lights are dim until you rev the engine. The battery light is also on, but very faintly. I have done the big 3 already. I tested the voltage and everything seems to check out, 12.5-12.7v at rest and 14.4v when running. Also the voltage doesn't change when I rev the engine. So is it just not kicking out the amps that it should? Should I send it back? It is suppose to make 80 amps idle and 165 at highway.
