Electronics Fundamentals: Electrical Measurements

Modern vehicles use many electronic controls. Diagnosing faults can be more difficult for technicians who have not had the benefit of training in electronics. This can lead to the replacement of unneeded parts, angry customers, and frustrated technicians. The goal of this training series is to prepare technicians to diagnose and repair vehicle electronic systems successfully. Each training segment will reinforce the concepts taught with exercises and a case study.

The goal of this installment is for technicians to be able to perform accurate DC circuit measurements and to be aware of how coils are used as electromagnetic devices that control typical vehicle components.

After completing this training, a technician will:

  • Be able to make accurate DC circuit electrical measurements
  • Understand coils and inductance
  • Understand how coils are used to create magnetic fields
  • Understand capacitors and their function in automotive circuits
