Electrical 1

Course Description

This three-day intensive course assumes no prior diagnostic experience with automotive electrical systems. Placement is based on assessment, to ensure that our students are signed up for the most appropriate course. All classes are hands-on; students work on actual vehicles.

Class size: 4 students


We recognize that many professional technicians have an incomplete understanding of electrical fundamentals. A solid electrical foundation is a key prerequisite to success in our hybrid and EV courses, and of course, is invaluable when working on any vehicle in any shop.

Learning Objectives

  • Have a clear understanding of the properties of voltage, current, and resistance
  • Use current clamps and DVOMs to accurately measure amps and milliamps
  • Know the difference between available voltage and voltage drop measurements
  • Understand normally open, normally closed, and double-throw relay operation
  • Be able to calculate current through a fuse by measuring voltage drop
  • Understand current flow through series, parallel, and series-parallel circuits
  • Recognize normal and abnormal voltage readings for all of the above circuits
  • Set up a parasitic draw measurement on a vehicle, and evaluate the result
  • Find and analyze a wiring diagram and plan first steps if the circuit is inoperative
  • Properly repair damaged electrical circuits and replace electrical terminals
