Title: Test equipment and motor windings for grounds, opens, and shorts.
Course: Heating, Ventilation, Air Conditioning, and Refrigeration I (17056-I) > Section: Understanding Basic Electricity

Test should include checking readings for grounds, opens, and shorts (checking common, start, and run terminals on a compressor), using an ohmmeter and megohmmeter, and observing safety procedures.

Process/Skill Questions:

- Why should the ground, open, and short be tested?
- How should a compressor/motor for a ground, open, and short be tested?
- Why is it important to test the compressor windings?
- Where are the start, run, and common terminals located on a compressor?
- How is the resistance in the windings determined?
- What is the purpose of a megohmmeter?
- What are the dangers of using a megohmmeter?
