Voltage Drops at stop lights after pulley install....help well i love my pulley dont get me wrong here....but i noticed at stop lights the voltage meter will drop down to around the 10-11 area.....as soon as i start going again its fine....i went with the powerbond as u can see in my sig....also in park the voltage seems normal......last night i was pulling out of the driveway and had the headlights on and everytime id touch the brakes the lights would dim out until i let off....any voltage boosters or anything i can do here at home to help this?

i can do a better alternator probably...any suggestions or links to where i can pick one up?.....is the diablosport predator tuner capable of bumping the idle up?.....if it is i might just go that route even though its going to hurt my pocket it will probly be good for the car because my fuel trims need tuned too.

I personally would never do an underdrive crank without overdriving the alt.........bumping the idle up to make up for an underdriven alt is a bandaid and rather well....dumb on an auto car because now you are putting extra load on the converter/brakes at the stop light........

should be able to.......I would THINK the ASP size belt would fit with your under drive pulley but I would get them from Napa/AutoZone/etc. and buy a size larger and a size smaller just to make sure you didn't get stuck....then take the belts you don't use back (if all my rambling made any since)....
I have the same problem but really its nothing to worry about. Your battery is not going to die from this. One thing else you could try is using led bulbs on all the brakes and running lights they use significatly less voltage to run than the stockers.
