How can you tell if a voltage regulator is bad?

With your car still in park, slowly press on the gas until your car reaches 1,500-2,000 RPMs. Read the output on the multimeter. The regulator should cap the output of your battery at around 14.5. If the voltage reads over 14.5, it probably means that you have a faulty regulator.

Will a bad voltage regulator drain a battery?

A bad voltage regulator can severely damage your car battery, causing it to stop working. … The voltage regulator ensures that steady charging voltage and power are delivered to the vehicle battery and other electronic components.
