AT216 Technical Writing Assignments
You will be required to successfully complete SIX technical writing assignments as part of the
writing to learn requirement of this course. A description of the writing assignments is outlined
The writing assignments will be used to reinforce and demonstrate your understanding of
electrical circuit analysis by giving you the opportunity to explain your diagnostic
reasoning in solving electrical circuit problems.
You will present your thoughts in a format similar to what you might present as a service
representative of a major automotive manufacturing or service corporation to factory
engineers or service technicians.
Your writing should be in a “professional voice”, specific and thorough in explaining the
problem, your analysis, conclusions and recommendations to correct the problem.
The focus of your writing should be explaining the operation of the electrical circuit,
identifying the possible problem areas and explaining your analysis of the circuit and how
to correct the problems.
Reasons & Evidence:
Your report should include reference to electrical circuit theory and laws governing
electrical current in circuits and how they apply to the problem in the electrical circuit.
You should include possible open circuit conditions, shorts to voltage, shorts to grounds
and possible high resistance areas of the circuit that would cause the condition in
Support & Organization:
Your conclusion(s) should identify the possible fault(s), followed by and explanation of
why the fault would cause the condition and how you would test your hypothesis to
confirm the fault in the circuit. You should also explain your testing strategy. Including
what fault would be the most likely cause and the order you would perform tests to find
the problem in the shortest amount of time with the least amount of effort.
You will receive a circuit wiring diagram along with a customer complaint describing
the problem related to the circuit.
Use the color coding technique learned in class to identify each portion of the circuit
and discern how the circuit is supposed to work.
Review the customer complaint and use the color coded circuit to diagnose possible
faults in the circuit that would cause the described problem. You may want to circle
the items or portions of the circuit for later reference. Attach to your written report.
Write the report in A.P.A. format. Your report should include the following:
Identify the customer complaint or problem.
Describe the normal function of the circuit and how it works.
What type of circuit is it?
How is it controlled?
What devices are controlled and operated by it?
Identify at least three possible faults that would cause the problem and explain
why each fault would cause the customer complaint.
Describe any tests you would perform to confirm that each identified fault exists
in the circuit.
For each fault listed, describe the best corrective action to repair the fault.
Discuss the diagnostic strategy you used to identify the possible faults. Include
the order in which you would test the faults and why you would test them that
way. You should also identify the most likely fault and explain why you believe it
to be more likely than the others. Finally, assuming this likely fault occurs
frequently in this circuit, write a recommendation to improve the circuit design.

To make an appointment:
For on-line assistance:
The vehicle’s horns stay on continuously. The owner thinks the horn relay may be stuck in the on
position. Specifically describe how you would test the horn relay in this case. Additionally,
besides the horn relay, describe three more circuit faults that would cause the horns to remain on.
Indicate specifically how you would test for each fault and the action needed to correct each
