1.Verify that the engine RPM is normal. See the Engine RPM Adjustment Procedure.
2.Start the machine and place the idle switch in the high position. See Figure F.9.
3.Check for AC voltage between the neutral stud on the control panel bottom and the #3 lead connection at the CB1 circuit breaker. Also check the voltage between the neutral stud and the #6 lead connection at the CB1 circuit break- er. Voltage should read between 115 and 130* volts. See wiring diagram.
4.Check for AC voltage between leads W1 and W2. See Wiring Diagram. Voltage reading should be about 64*VAC. Also check for AC voltage between leads W3 and W4. Voltage reading should be about 62*VAC. See wiring digram.
5.If the voltage is not present or is significantly dif- ferent from expected readings, check the wiring between test points and the stator winding. See wiring diagram. If the wiring is in good condi- tion, the stator is defective.
*Voltage shown is for a stator that is at normal full load temperature. Readings will likely be slightly higher if machine is cold.
