Application
This unit of competency defines the skills and knowledge required to assess the operation, test and repair starting systems requiring the use of amps, voltage and resistance (AVR) test equipment.
Where soldering of wires/connections is required unit MEM05001 Perform manual soldering/desoldering - electrical/electronic components should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
