PURPOSE OF THE UNIT STANDARD 
People in the field of manufacturing and engineering require the skills, values and knowledge reflected in this unit standard.
The learning outcomes in this unit standard also contribute to the exit level outcomes required for various manufacturing and engineering qualifications. The learner is capable to read and interpret charging system diagrams, know the components and remove, diagnose, test and replace conventional automobile charging systems in accordance with workshop and manufactures procedures. This will contribute to the exit level outcomes required for the National Certificate in maintaining vehicles and related qualifications.
