Student Guide for Written Knowledge Assessment Overview of Assessment This is a written assessment task you will be assessed on your knowledge of diagnosing and repairing automotive electrical systems. The topics that will be covered in the assessment are: ⦁ Prepare to diagnose and repair automotive electrical systems ⦁ Diagnose automotive electrical system ⦁ Repair automotive electrical system ⦁ Complete work processes This assessment will ensure that the elements, performance criteria, performance evidence and knowledge evidence required, and conditions are adhered to demonstrate competency in this unit assessment task. ⦁ Read the assessment carefully before commencing. ⦁ Your Assessor will use the assessment criteria in this document and will provide feedback / comment. ⦁ You MUST answer all the questions in the assessment tasks in your own words ⦁ This is an “Open Book” assessment, and students can use the resources listed in the “Resources Required” section below. Task/s to be assessed To complete the written assessments, you will need to answer 109 questions in total. Assessment 1 Quiz Questions will be completed using your Canvas account. The assessment has 67 questions comprising of Multiple Choice, True and False and Fill-in the Gap questions Assessment 2 Short Answer Questions will be completed using this document a has 42 Short Answer questions. Time allowed On average, Assessment 1 Quiz Questions and Assessment 2 Short Answer Questions should take 4 – 6 hours to complete. Location This theory assessment will be completed in a classroom under the supervision o a trainer/assessor. 2

Decision making rules To receive a ‘satisfactory’ outcome for this assessment students MUST successfully answer all questions. If a student achieves less than 100%, they can reattempt the assessment after further study has taken place. Students who cann achieve a minimum of 100% you will not have satisfactorily completed this assessment Your assessor will be looking for the following in this assessment task: - ⦁ methods to locate and interpret information required to diagnose and repair automotive electrical systems, including: ⦁ information provided by customers and supervisors ⦁ manufacturer specifications and procedures or equivalent documentation ⦁ workplace procedures required to diagnose and repair automotive electrical systems, including: ⦁ establishing serviceability of tools and equipment ⦁ documentation procedures ⦁ housekeeping procedures, including: ⦁ examination of tools and equipment ⦁ storage of equipment ⦁ identification, tagging and isolation of faulty equipment ⦁ disposal of excess materials ⦁ recycling procedures ⦁ Work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing automotive electrical systems, 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 system ⦁ Operating principles of automotive electrical systems and associated components including: ⦁ Current, voltage, resistance and power ⦁ Series circuits ⦁ Parallel circuits ⦁ Series and parallel circuits ⦁ Ohm’s law ⦁ Faraday’s law ⦁ Kirchhoff's law ⦁ Magnetism and direct current (DC) motor operation ⦁ Electromagnetic interference and radiation ⦁ Cable types and sizes and current carrying capacity ⦁ Circuit protection devices ⦁ Purpose and operation of automotive electrical systems and components, includin ⦁ Wiper motors ⦁ Electric windows ⦁ Electric door locks ⦁ Fan motors ⦁ Horns ⦁ Lighting ⦁ Radio aerials ⦁ Diagnostic testing procedures for automotive electrical systems, including: ⦁ Visual, aural and functional assessments of electrical system components including: ⦁ Component damage and wear ⦁ Component or connector corrosion ⦁ Component water or moisture ingress ⦁ Common faults in electrical circuits, including: ⦁ Open circuits 3

Assessment conditions 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 electrical systems that they have worked on, e.g. repair orders. Assessors must verify performance evidence through questioning on skills an knowledge to ensure correct interpretation and application. The following resources must be made available: ⦁ automotive repair workplace or simulated workplace ⦁ workplace instructions ⦁ manufacturer automotive electrical system specifications ⦁ three different vehicles or machinery with electrical system faults ⦁ diagnostic equipment for electrical systems, including multimeter ⦁ tools, equipment and materials appropriate for repairing automotive electrical systems, including: ⦁ automotive wiring ⦁ heat shrink ⦁ soldering iron Resources required Learning Resources available to students include: ⦁ Automotive Technology (A System Approach) 7 th Edition – Chapters 2, 5, 6, 7, 16, 20, 23 & 27 ⦁ Trainer Handouts Results/Re- assessment ⦁ The Assessor will grade the assessment and record the result on the front page o this document. (S) Satisfactory if all questions are correct and (NS) Not Satisfacto if any questions are left incorrect. ⦁ Feedback will be provided on either result. ⦁ Where a student receives a ‘NS Not Satisfactory’ result, the assessor will discuss the questions that are incorrect, and an opportunity given for re-assessment. ⦁ Students are provided with 3 attempts for the knowledge questions. Reasonable Adjustment If the participant is unable to undertake the written assessment as designed, an interview (verbal questioning) may be used as an alternate approach. 4

Assessment 1 – Questioning Written Assessment Q1. What four [4] important items of personal safety equipment (PPE) are worn when diagnosing and repairing automotive electrical systems? ⦁ Gloves ⦁ Eyes Glasses ⦁ Hard Hats ⦁ Lab Coastr Q2. To prevent personal injury or damage to the vehicle, you should always take the necessary precautions before working on or around a vehicle’s electrical system. You should disconnect the battery before disconnecting any electrical wire or component. Why? To work on a vehicle's electrical system, it is important to disconnect the battery before disconnecting any wires or electrical components to avoid damage to the vehicle or damage to yourself. This is because the battery provides power to the entire electrical system, and disconnecting it ensures that there is no active electricity flowing through the system while you work on it. Q3. What is a parallel circuit? In a parallel circuit, multiple branches are connected, allowing the current to divide among them. Consequently, only a portion of the total current flows through each individual branch. Although the voltage (or potential difference) across every branch in a parallel circuit remains constant, the currents within each branch may vary. 5

Q4. Describe the principle of “Faraday’s Law”? Faraday's Law of Electromagnetic Induction states that a change in the magnetic field within a closed circuit induces an electromotive force (EMF) or voltage in the conductor surrounded by the circuit. This induced voltage is proportional to the rate at which the magnetic field changes. In other words, the greater the rate of change of the magnetic flux, the greater the induced voltage. Q5. How is wire size determined? By the diameter of the conductor Q6. There are three [3] major factors that determine the proper size of wire to be used. What are they? ⦁ Choosing the appropriate wire diameter for a circuit is essential to ensure it can effectively carry the required current for the proper operation of load components, preventing issues related to electrical resistance and ensuring optimal performance. ⦁ Selecting a wire that can withstand anticipated vibrations is crucial to maintaining a stable and reliable electrical connection. This characteristic ensures the wire's resilience in the face of mechanical movements or environmental vibrations, preventing potential disruptions or damage to the overall circuit. ⦁ Selecting a wire with the ability to withstand anticipated heat exposure is crucial for preventing overheating issues and ensuring the safety and reliability of the electrical system. 6
