NOTE
During step 9, turn threshold control counterclockwise to lower ammeter reading and clockwise to raise
ammeter reading.
9.
If reading in step 8 was not within limits of 300 to 340
26
mA, adjust threshold control (27) and repeat step 8
27
until ammeter reads approximately 320 mA.

10.
Move joystick handle (7) fully to the left and observe ammeter reading. Reading should be between 600 and 640 mA.
NOTE
During step 11, turn max out control counterclockwise to lower ammeter reading and clockwise to raise
ammeter reading.
11.
If reading in step 10 was not within limits of 600 to 640 mA, adjust max out control (28) and repeat step 10 until amme-
ter reads approximately 620 mA.
12.
Turn starter switch off (TM 10-3930-660-10).
13.
Disconnect leads of ammeter. Secure electrical lead no. 53 to terminal A of top circuit board (21) with screw (25).
14.
Loosen screw (29) at terminal B of top circuit board (21) and disconnect electrical lead no. 54.
15.
Connect positive (+) lead of suitable ammeter to terminal B to top circuit board (21).
16.
Connect negative (-) lead of ammeter to disconnected electrical lead no. 54.
17.
Turn starter switch to the RUN position but do not start the engine (TM 10-3930-660-10).
18.
Slowly move joystick handle (7) to the right until indicator light (30) just comes on. Ammeter reading should be
between 300 and 340 mA.
NOTE
During step 19, turn threshold control counterclockwise to lower ammeter reading and clockwise to raise
ammeter reading.
19.
If reading in step 18 was not within limits of 300 to 340 mA, adjust threshold control (27) and repeat step 18 until
ammeter reads approximately 320 mA.
20.
Move joystick handle (7) fully to the right and observe ammeter reading. Reading should be between 600 to 640 mA.
NOTE
During step 21, turn max out control counterclockwise to lower ammeter reading and clockwise to raise
ammeter reading.
21.
If reading in step 20 was not within limits of 600 to 640 mA, adjust max out control (28) and repeat step 20 until amme-
ter reads approximately 620 mA.
