I installed an underdrive pulley (original crank pulley separated) about two months ago and have noticed an intermittent "problem"

actually i'm not sure if it really IS a problem.. here's what happens..

whenever i take a pretty tight LEFT turn, i get alternator warning lights like I did when the pulley first separated and the belt would stop spinning altogether..

it doesn't seem to happen on right-hand turns though. is this just a result of the underdrive? my little three-level LED battery indicator says that the battery is doing okay, generally in the top or middle of the charge meter (green or orange LED's)

anyone wanna chime in on this one?
