Process/Skill Questions:

- What is the function of each part of the ignition circuit?
- How does the movement of electrons through the ignition circuit generate ignition of the air/fuel mixture?
- How does the identification of an ignition part impact the decision to repair or replace the part?
- How does the engine date of manufacture (DOM) impact the part look-up process for determining a replacement part for the ignition system?
