The Professional Guide to Conducting a Voltage Drop Test

Voltage Drop Test: The Acceptable Voltage Drop Numbers You Must Know Quick Summary A proper voltage drop test on battery connections and a thorough one on starter circuits are the best ways to find hidden resistance that static voltage checks completely miss. To get an accurate reading, the test must be measured while the circuit is operating, not at rest. Ideally, voltage loss on either the power or ground side should not exceed 0.1–0.2 volts per segment. When voltage is lost in cables or connectors rather than across the load, … Read More
