About the Course:

This Aircraft Electrical Circuit Troubleshooting microcredential trains Aircraft Electronics Technicians to identify and troubleshoot basic electrical circuit faults using a digital multimeter and appropriate diagnostic procedures. 

Through immersive VR simulations, learners will troubleshoot a sensor circuit by identifying an unpowered section, measuring DC voltage, testing a fuse for continuity, inspecting wire connections, identifying an improperly stripped wire, and verifying the circuit after repair. The course emphasizes systematic fault identification, proper multimeter use, electrical safety, and accurate verification of circuit operation. 

Learners will practice following a structured troubleshooting process to locate faults, determine the cause of a circuit problem, safely correct the identified wiring issue, and verify that power has been restored to the circuit. 

Learning Objectives:

• Identify basic circuit faults using a systematic troubleshooting approach. 
• Recognize symptoms of a circuit section that is not receiving power.  
• Select and use the DC voltage setting on a digital multimeter. 
• Perform voltage measurements at designated circuit terminals. 
• Test a fuse using the continuity function of a multimeter. 
• Determine whether a fuse is conducting electricity or is open. 
• Inspect wire connections for improper stripping or poor electrical contact. 
• Identify wiring faults that can prevent power from reaching a circuit section. 
• Safely de-energize the circuit before performing wiring repairs. 
• Reconnect wires securely to their respective terminals. 
• Verify circuit operation after completing the repair.
