Should be around 7 volts with the motor running fast enough for the cutout to latch. When it does, the ammeter should show charging.

The absolute highest you should ever see the voltage (at the battery) with the car running is around 7.4 volts. MAX. That's not very good for the battery, but that's what you may see on a Model a generator. Ideally, the voltage should never exceed 7.1 volts, in a perfect world.

Typical resting voltage on the battery will be between 6.7 and 6.2 volts. But it should take close to 24 hours for the battery to settle down to that voltage.
