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, performance criteria, range of conditions and foundation skills:

test a basic electrical circuit, including:

one short circuit across an electrical resistive load

one open circuit before or after an electrical resistive load

one high resistance circuit before or after an electrical resistive load

current flow and voltage drop across an electrical resistive load

test for continuity in a basic wiring harness and visually check terminals in the wiring harness for moisture ingress and corrosion

carry out four different circuit repairs that include:

crimping various terminal sizes

soldering wire gauges to terminals

applying heat shrink insulation to crimped or soldered joints

replacing male and female terminals in a connector housing

performing terminal retention checks to replaced terminals.

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 basic electrical circuits they have tested and repaired, 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 electrical system specifications

vehicle or machinery with faults in the basic electrical circuits specified in the performance evidence

electrical test equipment to test basic electrical circuits and components

consumable materials relevant to repairing basic electrical circuits and components, including connectors, terminals, wire, electrical tape and heat shrink sleeving

electrical repair tools, equipment and materials relating to basic electrical circuits and components.
