7.If the voltage reading is low or not present, the generator field is not functioning proper- ly. Perform the Rotor Resistance Test. Also check the field diode rectifier bridge, fil- ter capacitor, and associated leads and con- nections. See Figure F.13 for location. See the Wiring Diagram.
NOTE: The normal flashing voltage is approx- imately 9VDC. This is battery voltage, which is processed and controlled through the engine protection board. This voltage must be present during
8.If the rotor voltage readings are normal, the field circuit is functioning properly. Install the left case side with the sheet metal screws previously removed.
