Voltage Drop PRO automatically tests vehicle wiring under load and measures voltage drop in the circuit. Real-time loaded and unloaded voltage readings are displayed. Switch modes to view readings from both sides of the circuit, pinpointing any excessive voltage drops. User-selected current draw allows the component current to be simulated. Volt Drop Pro won’t blow fuses or damage computers. The Wiggle Test feature operates continuously, aiding intermittent signal drop out detection.
