Set To SIM SAS (WO). (Cont)

TEST OR INSPECTION

CORRECTIVE ACTION

3. If multimeter indication is not correct, replace switch S16.

TABLE NO. 3-22. Multimeter Does Not Indicate 3.796 0.41 Vdc When LATL ACCLRM Control Is

Turned Fully Counterclockwise And Does Not Indicate -3.796 0.41 Vdc When LATL ACCLRM Con-

trol Is Turned Fully Clockwise.

TEST OR INSPECTION

CORRECTIVE ACTION

1. Connect multimeter between LATL ACCLRM SIM STAB 1 and SIG GND test

jacks. Go to 2.

2. Place LATL ACCLRM control to SIM STAB 1&2. Go to 3.

3. Turn LATL ACCLRM control throughout its range from fully counterclockwise (L)

to fully clockwise (R). Multimeter shall indicate 3.796 0.41 when LATL ACCLRM

control is fully counterclockwise and shall indicate -3.796 0.41 when LATL ACCLRM

control is fully clockwise. Digital multimeter shall indicate a continuously adjustable

voltage from counterclockwise to clockwise position.

Step 1. If multimeter indicates 0.0 vdc, go to 4.

Step 2. If multimeter indication is not correct, replace component board assembly A4.

Step 3. If multimeter indication changes abruptly from 4.20 to -4.20 vdc, replace

potentiometer R6.

4. Check switch S15 for continuity.

Step 1. If continuity exists, replace circuit board assembly A2.

Step 2. If continuity does not exist, replace switch S15.

TABLE NO. 3-23. Multimeter Does Not Indicate 1.0 6 0.2 Vdc With LATL ACCLRM Switch Place

To SIM STAB 1, SIM STAB 1&2, And SIM STAB 2.

TEST OR INSPECTION

CORRECTIVE ACTION

1. Turn LATL ACCLRM control for a multimeter indication of 1.0 vdc. Go to 2.
