Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements and performance criteria, range of conditions and foundation skills:

diagnose and repair a fault in two of the following starting system circuits in two different vehicles, vessels or machinery:

vehicle starter motor and solenoid circuit

vehicle ignition switch to solenoid control circuit

vehicle battery to starter motor circuit

machinery starting system circuit.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for:

using specialised tools and equipment

using appropriate personal protective equipment (PPE)

identifying hazards and controlling risks associated with:

working on high voltage ignition systems

wearing jewellery while working around high current wiring systems

operating principles of starting systems and associated components, including:

producing movement due to the force between magnetic fields

producing magnetic fields due to current flow through conductors

basic direct current motor operation, including simple armature, magnetic field and commutator

application, purpose and operation of starting systems and components, including:

removing and replacing faulty or damaged components

post-repair testing procedures for starting systems, including:

DTC clearing procedures

checking for electrical connector mating

static and dynamic performance tests of starting systems.

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 starting 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:

automotive repair workplace or simulated workplace

workplace instructions

manufacturer specifications for vehicle, vessel or machinery starting systems

two different vehicles, vessels or machinery with starting system faults

diagnostic equipment for vehicle, vessel or machinery starting systems, including multimeter

tools, equipment and materials appropriate for repairing vehicle, vessel or machinery starting systems.
