Question
How does voltage drop testing identify wiring harness faults?
Answer
It measures voltage loss across connectors or wires under load conditions.
Explain
Excessive voltage drop indicates resistance due to corrosion, damage, or loose connections. CHEPQ multimeters with automotive features perform voltage drop tests under load, revealing subtle wiring faults that normal continuity checks miss, preventing intermittent electrical issues and ensuring stable system operation.
