Mobile Equipment Electrical Troubleshooting

Learn to:

  • Correctly and safely use a digital multimeter (DMM)
  • Interpret equipment electrical schematics
  • Use a methodical approach to find open and short circuits in wiring harnesses
  • Isolate and replace defective electrical/electronic components
  • Avoid excessive use of jumpering

This course is designed to be the first step in rigorous, analytical electrical troubleshooting training for mechanics. A comprehensive review of basic DC electrical and electronic principles is included.

Using simulations, this course puts an end to the confusion that mechanics sometimes struggle with regarding electrical values and units such as ohms and milliamps. Students will work with switches, relays, pressure switches, potentiometers, solenoids, lamps, motors, PWM devices, diodes and more.

Participants will learn to maintain a multimeter and verify its operational condition before use. Detailed instruction will be given on how to configure and use a digital multimeter to make correct measurements safely and effectively.

Building on these basics, participants are challenged with hands-on exercises, and with computer simulations, to use efficient and logical methods to detect and diagnose common circuit faults such as opens, shorts and poor connections. Plenty of practice will be provided on reading and using electrical schematics for troubleshooting.

This 2-day, analytical course is taught with live equipment circuits (wiring harness training panels with components from heavy equipment such as Caterpillar, Komatsu, Hitachi, John Deere and more), troubleshooting simulation software and through instructor guided, hands-on study of the multimeter and various electrical components such as switches, potentiometers, relays and solenoids.

I learned where to go first [for troubleshooting], and to keep it simple.Brad P., Syncrude

Electrical/Electronics Basics

Objective: Explain basic electrical principles

Activities: Computer simulations to demonstrate electrical principles

Achieve clarity on your volts, ohms and amps for normal and faulted circuits!

Great content, covered most everything to troubleshoot the 24 VDC circuits. I really liked the hands on troubleshooting.Karalee K., Syncrude

Blended Learning

Objective: Create a classroom and lab dynamic where participants see, hear, do, solve, collaborate and experiment.

Activities: Discussions, hands-on fault finding and wiring work, computer simulations, learning games.

Technicians get the exploration time needed and the opportunity to stretch and learn.

The instructor kept things interesting and lots of interaction. Valuable course to take.Jason D., Teck Coal
