Can you suggest how I might check the amp output? I just called advance auto and Sears, and they both said all they can do is tell me whether its producing the right volts. Actually, Sears said all their diagnostic test can tell me is whether the alternator is "good or needs to be replaced." Whatever that means! A clamp on ammmeter would work, but I hate to spend $80+ for one of those just for this test. I already have a good multimeter, but it isn't the clamp-on type.

Thanks,
