Title: Check the applied voltages, circuit voltages, and voltage drops in electrical/electronic circuits using appropriate test equipment.
Course: Diesel Equipment Technology I (20107-I) > Section: Electrical/Electronic Systems: General Electrical Systems

Checking should include

- using the DMM as a voltmeter
- testing the light to check for power, ground, and test fuses.

The technician should demonstrate an applied understanding of voltage drop principles and be able to measure voltage drop.

Process/Skill Questions:

- How should a voltmeter be connected?
- What does high voltage and low voltage drop mean?
- What does a test light reveal about a circuit?
- Where should a test light not be used?
- What does a dim light indicate?
- What is the difference between a self-powered and a conventional test light?
- What happens if the wire casing is punctured while using test lights?
