The 87-91 System and the 92-99 systems are diffrent..
The 87-91 supplies the power to the Alt field via a 12v switched circuit..
On the 92-99'* the Power field is controled by the PCM... The PCM will change and or ramp up the power to the Alt depending on system load...
I have noticed a lot of the newer cars for exampl the 00+ bonneville will have 14+v all of the time... Other GM products are similar...
On my 95 depending on the load of the system I can see low points of 12v( 13 is the usuall ) and high points close to 14.5..
On the 91 Bonneville its 14v all of the time... Just different systems on different cars

The worst example of the load on the car is a long stoplight on a rainy night. With the wipers, headlights, markers, and brake lights all on at once, the voltage drops and things kinda slow down. As soon as the car starts moving again, everything returns to normal.

I measured the power draw on mine once (engine off) and it pulls 24 amps.
