4. System check, to identify the problem
The system check consists of:
• Stator check
• Regulator Rectifier check
• Downstream check
5. Stator check: See Figure 7.19.
5a. Key OFF, unplug the stator from the regulator
rectifier.
5b. Check resistance through the stator using a dig-
ital multimeter set to read Ohms(Ω).
• It should be between 0.1Ω and 0.14Ω.
• A high reading indicates a fault in the windings.
• A low reading indicates a short in the windings.
• There should be a reading of O.L. (Open Line)
between either lead and the engine block.
• It is good practice to check the stator cold, and
again when the engine is at operating temperature.
As the winding warm up, the insulation can break
down and allow the wires to short out.
5c. Check the raw output of the stator.
See Figure 7.20.
• Connect a meter set to read Volts AC to the output
leads of the stator.
• Start the engine and advance the throttle to 3,000
RPM.
• The stator should produce at least 26 Volts AC In
some cases, output will be as high as 34 Volts AC
