|
|
3. Repair electrical system
|
3.1 Repair information is sourced and interpreted
3.2 Repair options are analysed and those most appropriate to the circumstances are selected
3.3 Repair tools, equipment and materials are selected and checked
3.4 Repairs and component replacements and adjustments are carried out according to manufacturer specifications, workplace procedures and safety requirements, and without causing damage to components or systems
3.5 Post-repair testing is carried out according to workplace procedures to confirm fault rectification, and any further problems detected as having been introduced during the repair process are rectified
|
|
4. Complete work processes
|
4.1 Final inspection is made to ensure work is to workplace expectations and vessel is presented ready for use
4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
4.3 Tools and equipment are checked and stored according to workplace procedures
4.4 Workplace documentation is processed according to workplace procedures
|
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Assessment Conditions
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 marine electrical systems 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:
- marine repair workplace or simulated workplace
- workplace instructions
- manufacturer electrical system specifications
- marine vessel with faults in the electrical systems and components specified in the performance evidence
- diagnostic equipment for marine vessel electrical systems
- tools, equipment and materials appropriate for repairing marine vessel electrical systems.
