Electrical Module 1 (DVOM Tests of Electrical Circuits) Training Class
This hands-on program focuses on how to troubleshoot vehicle electrical problems with a digital volt/ohm meter (DVOM) to quickly find electrical faults in components or their related circuits. OEM code repair charts direct technicians to test for grounded, open or shorted circuit condition in the brake, engine or transmission controller wiring. In this course, hands-on classroom instruction covers steps outlined by vehicle manufacturers. The operation of vehicle circuits is explained in detail along with how they should be tested with a DVOM.
In this course, technicians learn by applying classroom theory to real testing on the electrical simulators using their own electrical test equipment (their own DVOM).
Learning Objectives
All students will receive the following information:
- Digital volt/ohm meter theory of operation
- How to measure a voltage source and its potential
- How to measure voltage drop and DVOM impedance
- How to test common series and parallel circuits
- How to test switch contacts with your DVOM
- How to test PCM parasitic draw with your amp meter
- How to test potentiometers and thermistor circuits
- How to test the continuity of wires in a wire harness
- How to isolate components for resistance tests
- How to measuring these common MAF sensor signals (Bosch Hot Wire, AC Delco, Karman Vortex)
- How to test fuel injector and ignition reference signals
- How to catch voltage spikes with the Min/Max function
- How to test PCM Class 2 and UART circuits for faults
Prerequisites
All students should have some previous training and experience in automotive electrical/electronics theory and application. They should also have some "hands-on" experience with their own DVOM.
Target Audience
Automotive repair technicians, service managers and writers, fleet managers and instructors.
