Hey, ran the test. Alternator is fine. The voltage regulator is new out of the box. But what I thought of was strang but true. I'm running Vbelts. Say the crank pulley to alternator pulley ratio is 4:1, now lets say the ratio on a serpentine setup is 6:1.... the alternator is going to put out more power when spinning faster. The slowest it will spin is at idle. I was thinking that the voltage regulator might be calibrated to work with these different situations. I tried an voltage regulator for an 80 F150 and what would you know but now I've got 14.1 volts.... Thanks guys.
