This unit describes the skills and knowledge required to diagnose electrical faults in recreational vehicles and report the outcomes to the customer and/or supervisor with recommendations about the next steps. Faults may require specialist or technical expertise.The unit includes diagnosing faults with electrical systems and equipment, but only those that are extra-low-voltage: not exceeding 50 V AC or 120V ripple-free DC, as defined in AS/NZS3000. The unit does not address diagnosing faults in mechanical components: propulsion, suspension, steering and braking systems.The unit applies to a person working in a recreational vehicle service and repair facility who undertakes routine tasks according to job instructions, plans/specifications and procedures and uses discretion and judgement in selecting equipment, services and contingency measures. They work with a high degree of self-direction and limited supervision. They apply known solutions to routine problems and report non-routine problems according to procedures. They are responsible for their output and have limited responsibility for the output of others.No licensing or certification requirements exist at the time of publication.
