• determining the cause of the problem, using diagnostic tools and/or equipment
• isolating the cause
• taking steps to reduce or eliminate the chance of electrical fire or other danger.

Process/Skill Questions:

• What precautions should be taken before troubleshooting?
• How does one determine which diagnostic tool or equipment to use for troubleshooting?
• How do the amps, current, voltage, and resistance measurements differ between a series and parallel circuit?
• How do volts change when measuring a series vs. a parallel circuit configuration?
• How are amps affected when comparing a series and a parallel circuit?
