What should the battery voltage be on a Ford PowerStroke?

The 12.6 that I note is with the key off and checking the voltage directly at the battery with a voltmeter. A fully charged 12v battery should be at 12.6 as each cell is 2.1 volts. If a battery at rest is showing 12.35 volts, it’s only 75% charged and 12.1 is at 50%. Get into 11.x range and I doubt the motor will even crank.

What should the voltage be on a 6.0L diesel engine?

Average running voltage on my 6.0L was 14.2 volts. I’d suggest looking into another alternator or running a monitor to watch live output numbers (voltage meter) that are being run through the system. 9.8 volts is far too low, and cold starting a diesel with low voltage is hard on an engine and computer components. When are you seeing the 9.8v?

What is the voltage of a car battery?
