Well thats what I thought, but someone has said that at tickover it draws 9v the same as the gto's, and on the hump it can draw as much as 13-14.2v it varies, hence the reason for the querie...lol

a lot of the voltage difference is down to the alternator current rising in line with the engine rev's , the proof of how hard it's working is the amount of amps it is drawing.
i have read a thread some where on here about the voltage varing as you have said and there is some sort of re wire mod to allow max voltage using a relay,but amp wise you can check by removing the fuel pump fuse and running it through a meter but would estimate about 4amp. :rolleyes4
