30.

Slowly move joystick handle (7) rearward until indicator light (32) just comes on. Ammeter reading should be between

300 and 340 mA.

NOTE

During step 31, turn threshold control counterclockwise to lower ammeter reading and clockwise to raise

ammeter reading.

31.

If reading in step 30 was not within limits of 300 to 340 mA, adjust threshold control (33) and repeat step 30 until

ammeter reads approximately 320 mA.

32.

Move joystick handle (3) fully rearward and observe ammeter reading. Reading should be between 600 and 640 mA.

NOTE

During step 33, turn max out control counterclockwise to lower ammeter reading and clockwise to raise

ammeter reading.

33.

If reading in step 32 was not within limits of 600 to 640 mA, adjust max out control (34) and repeat step 32 until amme-

ter reads approximately 620 mA.

34.

Turn starter switch off (TM 10-3930-660-10).

35.

Disconnect leads of ammeter. Secure electrical lead no. 55 to terminal A of bottom circuit board (22) with screw (31).

36.

Loosen screw (35) at terminal B of bottom circuit board (22) and disconnect electrical lead no. 56.

37.

Connect positive (+) lead of suitable ammeter to terminal B of bottom circuit board (22).

38.

Connect negative (-) lead of ammeter to disconnected electrical lead no. 56.

39.

Turn starter switch to the RUN position but do not start the engine (TM 10-3930-660-10).

40.

Move joystick handle (7) forward until indicator light (36) just comes on. Ammeter reading should be between 300 and

340 mA.

NOTE

During step 41, turn threshold control counterclockwise to lower ammeter reading and clockwise to raise

ammeter reading.

41.

If reading in step 40 was not within limits of 300 to 340 mA, adjust threshold control (33) and repeat step 30 until

ammeter reads approximately 320 mA.

42.

Move joystick handle (7) fully forward and observe ammeter reading. Reading should be between 600 and 640 mA.
