Thank you everyone.
I think I will try to find a place where I can upgrade my existing alternator before taking things apart.
Kai, you got a great deal! I was impatient and bid on the closest ending date one, I paid $20 for a used unknown brand one, and it took 2 weeks to get to my home.
Just went to Sears in Burbank last week (father's day sale), and saw the Engine Analyzer IN STOCK and on sale!
Going to get a timing light, but the price really scared me - $100??
