If any one or more of the readings are missing or not within specifications, then check for loose or broken wires between the test points and the sta- tor windings. See the Wiring Diagram. Make sure that the windings are NOT grounded inter- nally to the stator iron. If the leads are intact, then the stator may be faulty. Replace the stator.
If the voltage readings are within specifications, then the windings are good and functioning prop- erly.
7.If finished testing, perform the Case Cover Replacement procedure.
To test the stator weld windings:
1.Locate the weld winding leads connected to the
2.Check for approximately 58 - 65 VAC from W1 to W2. Also check for the same voltage from W2 to W3 and from W1 to W3.
3.If any of these voltages are low or missing, perform the Flashing and Rotor Voltage Test and also the Rotor Resistance Test.
4.If the tests in Step 2 are OK and the stator voltages are low or missing, the stator may be faulty.
5.If finished testing, perform the Case Cover Replacement procedure.
