I replaced my Alternator with the Delco 105 amp unit sold by PJ Grady. It works flawlessly and the voltmeter never drops below 13 amps even with A/C and the headlights running. You sound like you are having the same problem I had with the original Duceilier Alternator.

I have really noticed when I turn on the AC that some times at Idle the meter reads under 13 VOlts. Is that pretty common? Have any of you purchased a better alternator, or another fix? Thanks, C VIN 16367 >>
