Question: How do you hook up an amp meter on a car?

How do you check amp gauge?

Turn your multimeter to OHMS, disconnect the battery ground cable, and probe the 2 terminals of the ammeter. If you have continuity the gauge MAY be good. If you have NO continuity the gauge is definitely BAD. Do NOT swap the leads from the temp gauge!

What is your battery gauge supposed to read?

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.

Why is my ammeter not working?

To clarify this: In a multimeter, the current measurement function requires that you move one of the leads to (one of) the current measurement jacks. That jack will have a fuse in series with it somewhere within the multimeter. If the fuse is blown, the ammeter function will not work.

How should an ammeter be connected?

An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
