If you see your alternator voltage between 13 to 14 volts, that tells your car alternator is operating properly. . It was reading 13. 4VDC - below about 13. 30V (50%) 12. If the battery is new, then I would think the max charging rate of 14+ would be lower.

I monitor the voltage with a scan guage. To run the alternator at 50% the PCM runs a PWM at 50% duty cycle, this means the k20 terminal on the alternator will read around 6v. 5-volts.

Continue testing the regulated battery voltage, but start loading the system down.

Strange thing I have noticed now is even though the voltage is that low and the alternator is not putting out anything, the battery. High output alternator • 240-amp, 12-volt.

At first I noticed mostly when maneuvering in the parking garage - braking and turning. Battery was replaced about 1 month ago.

The very cheap alternator a bought 4 years ago stopped charging, so blaming that I replaced it with a Bosch one and having fitted it today it also does exactly the same thing.

Here's the story: If I charge the battery with an external charger, it will get to 13.

If it determines that a battery is at the proper level, it'll stop the charging. I used a charger to charge the battery. But after driving, voltage should go down to about 13.
