200
For your safety, these circuits are orange.
What are high voltage circuits, mostly found in Hybrids and Electric cars.
200
How to test for a parasitic draw.
What is place an amp meter in series with the power source of the circuit.
200
Method of using a test light to test fuses.
What is ground the test light and touch both contacts on the top of the fuses in the fuse box.
200

As judged by your awesome instructor.
400
Some vehicles require a tool to let the PCM know the battery has been replaced, what is this tool?
What is a scan tool with bi-directional control.
400
