99gatorbird

I have a 99 V6 firebird, 5-speed. I went to Autozone and this guy hooked up my car to their machine the Alternator was putting out 13.5-14.2 volts, and the peak amps was like around 6. He was like your alternator is bad because it should put out like 100 AMPS. Well their alternators were to expensive so i waited about a week, while my volt meter on the dash was fine stayed above 13. So i went to Advanced Auto and bought their ALT. for 90 dollars. After i put it on my car brought it up their to have them check it out. Well the new one was like putting out like 13.5-14.2 volts and the max ampage to the battery was like 12. Well we did about 2 more tests each test and the ampage was 7 and 10. Well we tested the old alternator on the machine on the inside of the store, it tested fine. So i got a refund on the one i bought and put the old one back on, we tested it again. The old alt tested 13.5-14.2 volts and about 11 amps this time. My question is did the original guy at autozone not know his machine to well and just want to sell me an alternator. I have read that these firebird alternators can hold up 100+ amps. Is this true. Does it sound like my old alternator is still good? Its a Delco on there now, i assume it is the original. Does anyone know about this? Thanks for all the help
