How many volts should my dash read?
Check the reading. A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
How do I test a 12 volt battery withOUT a multimeter?
If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights. If they are dim, that indicates the lights are running off the battery and that little or no charge is being produced by the alternator.
Where does the voltage meter in the dash show the battery?
The gauge is powered from the same circuit that provides switched 12VDC to all of the gauges, plus the AC components, safety switches and about everything that is powered up when the ignition switch is in the on position. It is a blue/white wire (according to this diagram) and comes from the fuse panel.
Is there a digital meter for AC volts?

What should the alternator voltage be with the engine running?
With the engine running it should be reading alternator voltage, should be around 14.4 DCV, that could vary depending on the needs of the electrical system at that time. If it is reading below 12.6 DCV with the engine running you are probably running off the battery. It will only run untill the battery dies, if the alternator is not charging.

How does the voltage meter in the dash work?
The gauge just monitors voltage at whatever point it is connected; none of your electrical system goes through it or relies on it for its operation. It’s the same as connecting the leads to your multimeter. You are testing voltage at that point but not affecting the system with the quality of the meter’s test leads.
How old is the voltmeter on the dashboard?
Bought a new battery, voltage gauge 14 while running, sounded a little slow cranking, about 10 volts charge indicated with engine off. Took it to be tested, 800 cca battery maybe 6 or 7 years old, 460 cranking amps. New battery as sub zero temps this week, and I like the car to start when I need it.
