4085-001 Cam System Motor/Sensor Service Check FRU 1 Motor does not work. Bat Wings do not move. Action Check the voltage at connector (J8) on the engine board. At pins 1, 2, 3, and 4 with the power on. There should be approximately +34 V dc on each pin to ground. If the voltage is incorrect, replace the engine board. If the voltage is correct, disconnect (J8) and check between pins 2 and 4 on the connector for approximately 7.5 ohms. If the reading is incorrect, check the continuity between pins 2 and 4 to the motor case. If continuity exists, replace the cam system motor. To check the sensor, check connector (J8) at pin 5 for approximately +4.9 volts. If voltage is incorrect, replace the engine board. If the voltage is correct, disconnect (J8) from the engine board and check for an ohm reading of 6.95 between pins 5 and 7. If the reading is not correct, replace the sensor. Note: If a short exists in the cam system motor, damage to the engine board drivers and power supply may occur.
