  • What a Voltage Drop Can Reveal. A voltage drop test basically means checking for the presence of unusually high (or unwanted) electrical resistance in wires, connectors, fasteners, components, and terminals.
  • How the Test Is Used. We'll use the simple diagram pictured above to illustrate the points in a circuit you are concerned with during a voltage drop test.
  • Applying Voltage Drop Tests to Common Automotive Problems. Okay, it's time to apply a voltage drop test to a common automotive electrical problem. We'll do a voltage drop on a starter motor circuit because the motor draws high amounts of current (above 100 amps) to operate, and a little unwanted resistance (like a loose or corroded terminal or connection) can easily upset circuit operation.
  • Testing Tips. When doing a voltage drop test, follow these important tips: Make sure your battery is charged and operating properly. Energize (activate) the circuit you want to test so that you have current flowing through it.
  • Testing Complex Automotive Electrical Circuits. The example circuit shown in Figure 1 is a simple series circuit. Mostly, you'll be dealing with series-parallel circuits.
