Seminars
Vestest offers seminars that help today's automotive technician understand today's technology. These seminars, of varying lengths, can be brought to your community and/or can be tailor-made for your service center.
Below is information about Joe's premier seminar on Voltage Drop.
Voltage Drop: Understanding, Diagnosis & Troubleshooting
A “Hands On” Class in Electrical / Electronic Testing
- Learn By Doing - Not By Watching
- Master the testing techniques that simplify the troubleshooting process.
- Get past the wrong! assumption: "Technicians already know that".
- Use Your Meter to troubleshoot live circuits.
- Test “switch-to-voltage” and “switch-to-ground” circuits to see:
- Where and how to begin testing based on symptoms.
- How to place your meter leads to get valid test results.
- Why incorrect lead placement and/or contact can give false test results.
- The correct way to locate voltage drops that affect circuit operation.
- How to do a “3-step” voltage drop test on any circuit.
- How to stay focused on the “current path” in parallel circuits.
- How to test “switched to voltage” and “switched to ground” circuits.
- How your test meter reacts in an open circuit.
- Why “unplugging the load” can give false test results.
- How to correctly test an open circuit.
- Why ”continuity” testing never means “able to pass current”.
- Why testing for voltage in an open circuit can cause you to replace a "good" part.
- Why “continuity” testing can cause you to replace a “good” part.
Learn:
- The correct use of the only valid ground point on any vehicle.
- Voltmeter and ohmmeter limitations.
- What to look for, after the repair, if the voltage drop is still excessive.
- How the vehicle’s “shared current path” system affects troubleshooting.
- How shared current paths can cause “no code set” drive-ability problems.
- How testing shared current paths first saves time and effort.
- How to test a relay when you don't have one to swap.
- How to test your meter to see if it is accurate enough to test today's vehicles?
- To pin point voltage drops that cause circuit problems
- How to avoid blowing a second fuse when looking for that short to ground.
- Where to start and end when looking for that short to voltage.
- How to quickly test a faulty switch or relay contact.
