Alternator?

I suggest you follow 67Darts advice... he's help my noob self plenty

if your not comfortable testing your alternator in the car you could drag the alternator into an oreily's and have them check um. sometimes testing the alternator in the car can be dangerous like if your alt is overcharging. but you cant always trust those people in oreilys to test your alternator correctly or have correctly working testing equipment (as i've learnt), haha. take it to two different oreilys if you can :)

yeah you've gone gold :) 67Dart =D>
