ELECTRICAL SERVICE NOTES
Keep the following notes in mind when diagnosing an electrical problem:
• All EFI component information and diagnostic testing procedures are located in the Fuel System chapter.
• Always refer to Digital Wrench when diagnosing a diagnostic trouble code.
• Refer to wiring diagram for electrical component resistance specifications.
• When measuring resistance of a component that has a resistance value under 10 Ohms, remember to subtract
meter lead resistance from the reading. Connect the leads together and record the resistance. The resistance of the
component is equal to tested value minus the lead resistance.
• Become familiar with the operation of your meter. Be sure leads are in the proper jack for the test being performed (i.
e. 10A jack for current readings). Refer to the Owner's Manual included with your meter for more information.
• Voltage, amperage, and resistance values included in this manual are obtained with a Fluke™ 77 Digital Multimeter
(PV-43568). This meter is used when diagnosing electrical problems. Readings obtained with other meters may
differ.
• Pay attention to the prefix on the multimeter reading (K, M, etc.) and the position of the decimal point.
• For resistance readings, isolate the component to be tested. Disconnect it from the wiring harness or power supply.
• Most electrical issues are related to damaged wiring. Fully test wiring before replacing any components.
