1. Open your car’s hood and locate the battery.

2. Using a voltmeter, touch the positive and negative terminals of the battery.

3. If the voltmeter reads 12 volts or higher, your battery is still alive. If it reads below 12 volts, your battery is dead and needs to be replaced.

How To Read Amps On An Analog Multimeter?

First, you need to understand what an amp is. An amp, or ampere, is a unit of measurement for electric current. In other words, it’s a measure of how much electricity is flowing through a given point.

Now that you know what an amp is, let’s talk about how to read them on an analog multimeter. To do this, you’ll need to use the multimeter’s ohmmeter function.

First, set the multimeter to the highest range possible. Then, touch the probes to the two points you want to measure the current between. Make sure that the probes are touching the metal parts of the multimeter, not the plastic parts.

The multimeter will now give you a reading in amps. The reading will be in milliamps (mA), which is one thousandth of an amp. So, if the multimeter reads “1.2 mA,” that means the current flowing through the two points is 1.2 amps.

If you want to be more precise, you can switch to a lower range. For example, if the multimeter reads “1.2 mA” on the highest range, you can switch to the next lowest range and get a more accurate reading.

Now that you know how to read amps on an analog multimeter, you can use this information to troubleshoot electrical problems or to just understand how much current is flowing through a given point.

Final Word

A 12 volt battery can be checked with a multimeter by setting the multimeter to the 20 volt DC setting. The positive lead of the multimeter should be touching the positive terminal of the battery, and the negative lead should be touching the negative terminal of the battery. If the multimeter reads 12 volts, then the battery is fully charged. If the multimeter reads less than 12 volts, then the battery is partially discharged.
