FLASHING AND ROTOR VOLTAGE TEST(CONTINUED)
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.12 for location. See
the Wiring Diagram.
NOTE: The normal flashing voltage is approxi-
mately 9VDC. This is battery voltage, which is
processed through the Battery board. This volt-
age must be present during start-up to "flash"
the rotor field.
8. If the rotor voltage readings are normal, the
field circuit is functioning properly. Replace
any cable ties cut during the test. Install the
right case side.
