This is a three part class on diagnosing electrical issues using a variety of methods and tools. This is the full-length version that includes:

Part I
The focus of this section is to develop a solid and repeatable testing routine, expectations of what you expect to see on your meter, navigating wiring diagrams, and understanding how different circuits work.

Part II
See how to set up your lab scope to put the picture of an electrical event on the screen. Learn a step-by-step process that can be applied to both Pico and Snap-On scopes. At the end, a case study is provided to show the importance of using the lab scope when scan data and voltmeter fall short.

Part III
The final part will take all the information and methods we’ve learned and apply them to real broken vehicles. Case studies will include Ford & Toyota vehicles and will show technicians how to diagnose a variety of faults such as fuse issues, diagnosing O2 heater circuits, CAN Bus & LIN Bus diagnostics.
