This course equips engineering personnel with the right approach to troubleshooting without guessing or using trial & error method. It eliminates wastage on components parts thus allowing only defective components to be replaced in the course of troubleshooting. Participants will also learn about the operation of electrical control components, testing and interpretation of technical specification on these components.
