Question
How to diagnose faulty automotive headlight ballast in HID systems?
Answer
Monitor ballast voltage output and test headlight operation.
Explain
A faulty HID ballast causes dim or inoperative headlights. CHEPQ tools measure ballast voltage output (20,000-30,000V) and test headlight ignition—replacing the ballast restores HID headlight functionality.
