Tone's right. Get a yellow top. It won't fix all your light dimming probs, but it certainly helped mine!
I tried to contact Rickster about his high amp alternator's (hoping one would compliment my system), but got no response. You planning on doing anything like that? If so, let me know who you go through (or where you find one...)
Word is, Bimati's going to be in town on Monday to hook up with you. Good time for dinner/drinks?
