Alternator Voltage

I have an 88 Camaro IROC-Z with the 350 TPI. Anyone know what the alternator output voltage should be? I seem to be getting anywhere from 15 to 15.5 Volts at the battery. Thanks

Re: Alternator Voltage

15 volts with the engine running with no head lights or the accessories on at about 1500-2000rpm is about normal
but after you turn on all the accessories, lights, air-conditioner, etc. it should be about 13.1-13.7 volts
