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

TM 1-6625-735-14

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. (Cont)

TEST OR INSPECTION

CORRECTIVE ACTION

2. Place LATL ACCLRM control to SIM STAB 1. Multimeter shall indicate 1.06 0.2

vdc.

Step 1. If multimeter indication is not correct, replace switch S15.

Step 2. If multimeter indication is correct, go to 3.

3. Connect multimeter between LATL ACCLRM SIM STAB 2 and SIG GND test

jacks. Go to 4.

4. Place PITCH RATE GYRO control to SIM STAB 1&2 and then to SIM STAB 2.

Multimeter shall indicate 1.0 6 0.2 vdc in each position. Go to 5.

5. If multimeter indication is not correct, replace switch S15.

TABLE NO. 3-24. Multimeter Does Not Indicate -3.05 6 0.33 Vdc When LATL ACCLRM Switch Is

Placed To SIM SAS 1.

TEST OR INSPECTION

CORRECTIVE ACTION

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

Go to 2.

2. Place LATL ACCLRM control to SIM SAS 1. Go to 3.

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

to fully clockwise (R). Multimeter shall indicate -3.056 0.33 when LATL ACCLRM

control is fully counterclockwise and shall indicate 3.05 6 0.33 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 changes abruptly from -3.38 to 3.38 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.
