well it was pooring rain and i turn into a local parts place to get some freon so i can do a leak test on my a/c. Well right when i get in a parking spot the car dies....then wont start. they test/check the battery =good. Then they check the alt. at idle and around 2000rpm and at idle the amps sometime dip into the negative. I was thinkin that it will run o.k, but i was makin it work, headlights, wipers, defroster, small amp, cd player. what do u guys think.
