What is the Best Multimeter for Automotive Repair
A multimeter is a tool that makes life easier when testing electronics or wiring in a vehicle.

Checking if a battery has a charge or testing the alternator are common problems that can be quickly checked with a multimeter.

A good meter for automotive work will have basic requirements that almost any meter should have.

Why is a Multimeter Used in Automotive Repair?

  • Checking Voltages
  • Best Multimeter for Automotive Repair
    A meter should be able to read voltage, mainly DC voltage since this is what a car’s electrical system runs on.

    Setting a meter to DC voltage and placing the leads on the positive and negative terminals will show a battery’s charge.

    When a battery is low on a charge, a battery charger can be used to give it a charge and then see if the battery is holding the charge or not.

    If it does not hold a charge, then it needs to be replaced.

    Another common use of a meter is to test if the alternator is working correctly. This is done by placing the leads on the battery terminals and while the car is running, watching what the voltage is.

    Most vehicles idle at around 14 volts which would indicate the alternator is good.

  • Check for Continuity (Open or Short)
  • What is the Best Multi meter for Automotive Repair Jobs Testing Voltage
    Continuity is simply testing if there is a break in a circuit or wire.

    For example, a fuse can be tested by putting the leads on both legs of the fuse. The meter will stay at zero if it is bad; if it is good, then it will show a number higher than 1.

    A good multimeter will beep while doing a continuity test which can help greatly in hard-to-reach components.

    A break in the wiring can also be checked to see if there is a bad inline fuse or a wire simply has a break in it.

  • Check Resistance
  • What is the Best Multimeter for Automotive Repair Jobs
    Resistance is testing how much an electrical current is being blocked from flowing through a circuit or wire.

    Measuring resistance is not used a lot in automotive repair but is still used in certain cases.

    For example, some fuel pumps can be tested for resistance to see if it is good or bad.

    If the resistance does not fall within a certain range and is too high or too low, it indicates that the pump’s fuel is bad.
