How To Use Analog Multimeter To Test Car Battery. Which is going to be VDC DC voltage and then find a number thats closest to the voltage of the battery that your trying to measure. To test a car battery with a multimeter first set the dial to the proper voltage range.
This is an optimum range for measuring batteries. Which is going to be VDC DC voltage and then find a number thats closest to the voltage of the battery that your trying to measure. Set Multimeter Ensure the ignition lights and radio are off.
In those cases a battery load test is good since the battery voltage versus time for the load applied can tell you of life left in.
Now start the car and look for a revised voltage over 10. Measuring the voltage of an alternator using a multimeter Turn off your vehicles engine and open the hood to get clear access to the battery. The negative lead is what keeps your car grounded. After doing this set the dial to 20 volts so you will be able to measure 0-20 volts.
