Check electrical circuits using fused jumper wires; determine necessary action
Recommended resource materials:
•

•
CDX Automotive Resource Kit
CDX eTextbook
Tech service bulletins, Shop manuals, and any other information applicable to the specific vehicle or components
you are working on.
Some safety issues to consider:
•
•
•
•
Be cautious around electricity. High voltage (enough to injure or kill you) is present on many vehicles. Ignition
systems, hybrid vehicles, and 42 volt electrical systems are just a few to be careful of.
Accidental deployment of the airbag system could happen if you inadvertently probe the wrong wire. Most
manufacturers use yellow colored wiring to denote wiring for the airbag system. Always be aware of the system/
circuit you are working on.
Always wear correct protective eyewear and clothing and use the appropriate safety equipment, as well as
fender covers, seat protectors, and floor mat protectors.
Make sure that you understand and observe all legislative and personal safety procedures when carrying out
practical assignments. If you are unsure of what these are, ask your supervisor/instructor.

Fused jumper wire
Vehicle or simulator
Assignment:
NB: The vehicle or simulator that will be used with this exercise should have an electrical fault. Please ask
your supervisor/instructor to identify which vehicle or simulator that he/she would like for you to use.
1.
Locate the appropriate service information for the vehicle/simulator that you will be working on. You will need the
disassembly and wiring diagram/s for the fault and its circuit/s.
2.
Disconnect the connector at faulted component.
What color is the wire that supplies power and/or ground to this component? ........................................................

a. With the jumper in place, did the load/component operate?
Yes / No
(Circle one)
b. Why – or why not?:
4.
Based upon your findings, what do you believe may be the fault/s of this circuit?
5.
Have your supervisor/instructor verify satisfactory completion of this task, observation found, and any necessary
actions recommended.
6.
Return the vehicle to beginning condition and return any tools that you may have used to their proper locations.
