Alternator Question

Well I have been putting a lot of money into my truck lately, and on my list was a new alternator. My lights have been pulsing (brighter to dimmer over and over) and my batteries are new so I went and got one from NAPA. My alternator that I had was putting out too much voltage according to the test NAPA ran. After I put my new one on my lights quit pulsing and my truck seems to run better. I can understand the lights, but my truck seems to just overall run smoother. Could anyone tell my what has happened?

One would think surges in currents could affect the whole system, but I'm not an expert.....

So bumping this up for ya.

I had a 2000 7.3, same symptons, long story short, new alternator. Lights quit pulsing and my dad (who's been driving it since I got my new 05) swears its better all the way around. I was thinking maybe without the voltage surges the ecm was getting good, clean signals to adjust everything as its running. Could be total b.s., but thats the best guess I can come up
