Question
How to diagnose faulty automotive wiring harness ground strap?
Answer
Test ground strap continuity and measure voltage drop.
Explain
A faulty ground strap causes electrical system faults. CHEPQ tools test ground strap continuity (0Ω) and measure voltage drop (<0.2V during load)—replacing the ground strap restores proper electrical grounding.
