ELECTRIC JOYSTICK ASSEMBLY REPAIR/TEST/ADJUSTMENT

TM 10-3930-673-34

NOTE

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

and clockwise to raise multimeter reading.

(h)

If reading in Step (g) was not within limits of 600 to 640 ma., adjust "max out" control (34) 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 #53 to terminal A of upper circuit board

(30) with screw (31).

(k)

Loosen screw (35) at terminal B of upper circuit board (30) and disconnect electrical lead #54.

(l)

Connect positive (+) lead of multimeter to terminal B of upper circuit board (30).

(m) Connect negative () lead of multimeter to disconnected electrical lead #54.

(n)

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

(o)

Slowly move joystick handle (5) to the right until indicator light (36) 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 (33)

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

(q)

Move joystick handle (5) fully to the right and observe multimeter reading. Beading 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 (34) 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 #54 to terminal B of upper circuit

board (30) with screw (35).

(u)

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

"threshold" (33) and "max out" (34) controls as required.
