• Explain electrical theory and concepts essential to troubleshooting

• Discuss the basic logic of series, parallel and series-parallel circuits

• Learn a systematic, “logical”, efficient method for electrical troubleshooting which can be applied to all systems

• Discuss safety precautions that must be taken when troubleshooting electrical malfunctions

• Identify the types of electrical malfunctions that might result, what meter readings would be obtained, and how circuit performance would be affected in a given circuit

• Read and interpret complex wiring diagrams

• Cite the characteristics of single-, and three-phase motors and their associated control components

• Identify motor problems – both electrical and mechanical

• Troubleshoot industrial motor control circuits

• Identify and discuss electrolytic corrosion

• Explain electrical fires and electrocution hazards
