ELECTRICAL SERVICE NOTES
Keep the following notes in mind when diagnosing an electrical problem.
SRefer to wiring diagram for stator and electrical component resistance specifications.
SWhen measuring resistance of a component that has a low resistance value (under10 Ohms), remem-
ber 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.
SBecome 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.
SVoltage, amperage, and r esis t ance values included in t his m anual are obt ained with a F luke¥ 73
Digital M ult imet er or a Tekt r onix DMM155. Bot h of t hes e m et ers are ac cept able for use when
diagnosing electric al problems. Readings obtained wit h other met er s may differ.
SPay attention to the prefix on the multimeter reading (K, M, etc.) and the position of the decimal point.
SFor resistance readings, isolate the component to be tested. Disconnect it from the wiring harness or
power supply.
