Alternator Recomendations
Alrighty, I've done some searching on this subject but didn't yeild an answer to my question. I have a 2000 Silverado with the 2005 e-fans. I have the stock 105amp alternator and I am expierencing a voltage drop (down to 9!!!) when the fans turn on high. This is with a Nelson Fan Harness. I am looking to solve this problem and I am thinkin that part of the cause is my alternator. So what alternator should I get, looking to shop at the local NAPA (napaautoparts.com). I have a slavage 145amp in my hands and it looks like the plugs are different what recomendations do you guys suggest. Should I also play around with the values for cooling fan airflow (Engine>Idle>Idle Airflow), what sould these values be? Thanks for all the help ahead of time.

What does your plug look like on your alternator, and what year 145amp did you get? On my truck the plug is a long rectangle,but on the 145amp it is almost a square.

Glad to here the dccontroller worked good-which model did you get? I may go this route instead of "wasting" money on an alternator that wont solve the problem.
So as far as the tuning portion of my question does anyone know what edit in Cooling Fan Airflow?
