hey guys i searched the threads and i can't find the answer.> Well a few days ago I installed BBK underdrive pullies, now i know that everybody says to get another alternator (3G), but i have also been told that if u don't have a huge music system u should be alright. so today I go to start the car and the starter solenoid just clicks and the car won't start, so my friend came and gave me a jump and it started right up, so i drove around for awhile and i had no problems with it dieing out, so i parked it, and i'd say about an hour later me and my friend came back out to start it and the same thing that happened before started again , now with the engine off i'm getting 12.03 volts,and when i try to start it, I have to jump it again.So I'm confused should i get the 3G alternator or should i get another battery, thanx for your help!!
