Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to return charging system alternators to original manufacturer tolerances and clearances. It involves preparing for the task, dismantling and evaluating the transmission, carrying out the overhaul process, reassembling and testing the transmission, and completing workplace processes and documentation.It applies to those working in an automotive service and repair industry. The charging system alternators include those fitted to agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycles or outdoor power equipment.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the charging system alternators that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

automotive repair workplace or simulated workplace

workplace instructions

manufacturer specifications relating to charging system alternators

two different vehicles, vessels or machinery with star and delta connected stators and requiring overhaul

tools, equipment and materials appropriate for overhauling and adjusting a range of alternators.
