ELECTRICAL SERVICE NOTES STATIC AND DYNAMIC TESTING
Keep the following notes in mind when diagnosing an There are many methods for testing a DC circuit. These
electrical problem. methods fall into one of two categories, either static or
dynamic.
• Refer to wiring diagram for stator and electrical
component resistance specifications. STATIC TESTING
The two most common forms of static testing are:
• When measuring resistance of a component that has a
low resistance value (under 10 Ohms), remember to • Resistance testing (the Ohms setting on your DMM)
subtract meter lead resistance from the reading.
Connect leads together and record the resistance. The • Measuring voltage with the circuit open, such as when

Voltage”.
• Become familiar with the operation of your meter. Be
sure leads are in the proper jack for the test being These two tests will help you find the majority of electrical
