ELECTRIC JOYSTICK ASSEMBLY REPAIR/TEST/ADJUSTMENT - continued

TM 10-3930-673-34

(h)

If reading in Step (g) was not within limits of 600 to 640 ma., adjust "max out" control (41) and

repeat Step (g) until multimeter reads approximately 620 ma.

(i)

Turn starter switch off (TM 10-3930-673-10).

(j)

Disconnect leads of multimeter. Secure electrical lead #55 to terminal A of lower circuit

board (37) with screw (38).

(k)

Loosen screw (42) at terminal B of lower circuit board (37) and disconnect electrical lead #56.

(l)

Connect positive (+) lead of multimeter to terminal B of lower circuit board (37).

(m) Connect negative () lead of multimeter to disconnected electrical lead #56.

(n)

Turn starter switch to the RUN position but do not start the engine (TM 10-3930-673-10).

(o)

Move joystick handle (5) forward until indicator light (43) just comes on. Multimeter reading

should be between 300 and 340 ma.

NOTE

During Step (p), Turn "threshold" control counterclockwise to lower multimeter reading,

and clockwise to raise multimeter reading.

(p)

If reading in Step (o) was not within limits of 300 to 340 ma., adjust "threshold" control (40)

and repeat Step (o) until multimeter reads approximately 320 ma.

(q)

Move joystick handle (5) fully forward and observe multimeter reading. Reading should be

between 600 and 640 ma.

NOTE

During Step (r), turn "max out" control counterclockwise to lower multimeter reading,

and clockwise to raise multimeter reading.

(r)

If reading in Step (q) was not within limits of 600 to 640 ma., adjust "max out" control (41) and

repeat Step (q) until multimeter reads approximately 620 ma.

(s)

Turn starter switch off (TM 10-3930-673-10).

(t)

Disconnect leads of multimeter. Secure electrical lead #56 to terminal B of lower circuit board

(37) with screw (42).

(u)

Repeat Steps (a) through (k) and check that current readings are still within limits. Readjust

"threshold" (40) and "max out" (41) controls as required.
