Hey tensely, You still got the stock alt in your Wag? If so, sometime upgrade to a CS-144 alt and you shouldn't have any issues. Previous owner did that to my Wag, and I got great power. Only time mine will dip is if all the lights(including fog's) are on, the AC is on high, and at a stop in gear at low idle.
From what i've read online, the stock alt is barely rated high enough for the stock GW. After a number of years and miles worth of use are on it, it is bound to get weaker with time and then, there ya go....low power
