CHARGING VOLTAGE QUESTION
Its important to note this is not voltage at the battery. This a test whether the regulator is doing its job based on the voltage it 'sees'. The voltmeter is connected from the junction at the ballast resistor to ground.
The factory considered up to 0.7 Volt difference from the alternator to the battery acceptable with 20 amps flowing from the alternator and about 15 amps through the dash ammeter to the battery.
When I look at the voltage on the automatic charger, the maintaining voltage is usually around 14 Volt.
Similar although slightly higher for the later regulator
