TEST PROCEDURE
1.With a 5/16” nut driver or socket, remove the 6 sheet metal screws from the case top.
2.Remove the rubber gasket (cover seal) from the lift bail.
3.Remove the fuel cap. The rubber gasket for the fill tube will come off with the case top.
4.Remove the case top, then replace the fuel cap.
5.Remove the screws holding the right case side.
6.Remove the right case side by lifting up and out.
7.Start the engine and set it to AUTO and wait for it to drop to low idle (2400 rpm).
8.Plug a trouble light with a 100 watt bulb into one of the 120VAC receptacles.
The machine should go to High Idle.
If it does not, measure the voltage across the toroid leads (260 and 261) at pins 3 and 4 of J2. See Figure F.6. It should be approximately 2.8VAC.
If the voltage is correct, the Control Board may be defective.
If the voltage is not correct, the toroid may be defective.
9. Shut the engine OFF.
NOTE: If the Toroid needs to be replaced, pay close attention to the direction that the various leads are routed through it. See the Wiring Diagram for exact instructions.
