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.
SWhenmeasuring resistanceofacomponent that hasalowresistancevalue(under10Ohms),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.
SBecomefamiliar withtheoperationofyourmeter . Besureleadsareinthe properjack forthetestbeing
performed(i.e. 10Ajack for current readings). Refer tothe Owner’smanual includedwith yourmeter
for more information.
SVoltage, amperage, and res ist anc e values included in t his m anual are obt ained wit h a Fluk eâ„¢ 73
Digital M ult imet er or a Tektronix DMM155. Bot h of t hese meter s are accept able for us e when
diagnosing electric al problems. Readings obt ained with 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.
