How do you know your alternator is fine and charging the battery?

What is the voltage across the battery when the car is running with no load?

The voltage is at 14.25 with no load and at the alternator it is at 14.30.The engine is not the stock one. I blow up the stock lx engine and put a stock ex engine.

No would that make the battery light come on and stay on for two days.
