"The main reason for my post was to see if a bad battery will show 14v at the post while running."

When you see 14V at the battery (or basically anything above 12V) it's coming from the alternator to do two things:
1) Charge the battery
2) Be propagated to the rest of the car's electrical system as needed.

With the car running, the voltage at the battery has little to do with the battery, except to charge it.
