How to Test a Car Battery? To measure battery load, conduct three voltage tests with the multimeter. Start the first test by making sure the vehicle is turned off. Multimeters have two probes: red and ...

For all of you who have a multimeter thrown in a drawer or toolbox but don’t know how to use it, these instructions will help in your search for missing voltage.
