Application
This unit describes the performance outcomes required to inspect, test and service vehicle, vessel and machinery charging systems. It involves preparing for the task, inspecting charging systems, servicing the systems, and completing workplace processes and documentation, including any associated recommendations for further action.
It applies to those working in the automotive service and repair industry. The charging systems include those in agricultural machinery, heavy commercial vehicles, light vehicles, vessels, motorcycles, mobile plant machinery or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Evidence of Performance
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:
inspect, test and service the charging systems of three different vehicles, vessels or machinery, in which the work must involve checking:
system output
system control circuit
system wiring.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to inspecting, testing and servicing charging systems, including procedures for:
selecting and using personal protective equipment (PPE), including clothing, and eye and hand protection
working safely with high current electrical systems
environmental requirements, including procedures:
found in safety data sheets (SDS) relating to toxic and corrosive substances
for recycling and disposing of replaced charging system components
identification and function of charging system components, including:
battery types, including:
lead acid and deep cycle batteries
maintenance-free batteries
generators
alternators
basic operating principles of charging systems, including:
using mechanical energy to produce electrical energy
charging battery and supplying power demands of vehicle
inspection procedures for charging systems, including visual, aural and functional assessments of:
component damage and wear
component corrosion
testing procedures for charging systems, including:
accessing electrical terminals and using test probes without damaging connectors, fuse holders or wiring
measuring charging system output under load
servicing procedures for charging systems, including:
changing and adjusting drive belts
cleaning and tightening terminals
checking gauges and warning devices for operation
post-service testing procedures, including confirming that charging system is operating to manufacturer specifications.
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 charging systems that they have inspected, tested and serviced, 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 charging system specifications
PPE, including clothing, and eye and hand protection
three different vehicles, vessels or machinery with charging systems requiring servicing
tools and equipment appropriate for inspecting, testing and servicing charging systems, including multimeter.
