What is this unit standard about?
This unit standard is for people in outdoor power equipment and motorcycle engineering industries.
People credited with this unit standard are able to:
- demonstrate knowledge of capacitor discharge ignition systems (CDI) on small engines and motorcycles
- demonstrate knowledge of a transistorised magneto ignition system
- test flywheel magneto ignition systems and their components for faults
- rectify faults on a flywheel ignition system.
Should I have completed any other unit standards first?
We recommend you should have completed unit standard 235 (Describe automotive ignition systems and their operation) or be able to demonstrate equivalent knowledge and skills.
How will this unit standard be assessed?
You will be required to:
- prove your theory knowledge of the circuit layout and operation of CDI systems on small engines and motorcycles
- prove your theory knowledge of the circuit layout and operation of a transistorised magneto ignition system
- test flywheel magneto ignition systems (circuit breaker or CDI) and their individual components for faults
- rectify flywheel ignition system faults, assemble, adjust, and retest.
This will involve completing the following types of assessment:
- case study
- workplace report
Special tools and equipment or range of work required
You will need:
- a multi-meter
- access to motorcycles or small engines with flywheel ignition system faults.
