Course: Automotive Technology III (20104-III) > Section: ELECTRICAL/ELECTRONIC SYSTEMS: Lighting Systems

Diagnosis should include testing the bulb for

- continuity and wattage
- voltage source
- ground
- terminal fit/connection
- resistance in the wiring (voltage-drop test).

Process/Skill Questions:

- What would cause a brighter-than-normal light?
- How would a loose connection affect the light?
- How would high resistance affect the light?
