What you will study
Ignition and automatic demand
Trace DC conversion, two high-energy branches, torque-pressure sensing, arming and annunciation. Distinguish shared switch packaging from proof of its independent functions.
Starter and generator interfaces
Connect relay control, field protection, cross-start current limiting and generator transition. Compare isolated spark rates, commutator depth, brush wear and relay-test chronology.
Practice and demonstrate understanding
Eight lessons, six prediction-and-Apply exercises, eight two-stage cases, a required measurement bench and twelve independent decisions provide 24 lab requirements. The independent review requires every critical decision. A separate 40-question final requires 80%; the certificate requires all learning activities.
Learning outcomes
- Explain how the exciter supplies two independent ignition branches.
- Trace arming, torque switch demand and annunciation without treating the lamp as spark proof.
- Distinguish starter feed, transient protection and generator output controls.
- Interpret measured records and preserve each unresolved component finding.
