ELECTRICAL SERVICE NOTES
Keep the following notes in mind when diagnosing an
electrical problem:
• Refer to wiring diagram for stator and 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.
