Presented by Dave Duggan, this continuing education module provides a fundamental look at the conventional Signal circuit, reviewing the circuit operation using blocking diodes and polarity reversal.
An investigation of an open circuit fault in an older style of installation follows, using resistor substitution, circuit splitting and voltage/resistance readings to track down the fault.
This is more suitable for the newly registered technician who may not have had the experience of using a meter, following a circuit layout, and splitting to locate a problem
There is also a short quiz at the end of this course to test your understanding of the materials presented.
Complete the course and achieve a score of 70% or higher on the quiz to receive 1 Category 1 credit. Scores below 70% will receive 0.5 Category 2 credit upon course completion.
Please note that CFAA allows one quiz attempt per course. We encourage you to review all course materials in full before proceeding with the quiz to ensure you are fully prepared.
