TABLE NO. 3-35. Multimeter No. 1 Does Not Indicate -1.3 6 0.3 VDC When SAS SYSTEM YAW RATE Control Is Turned Fully Counterclockwise And Does Not Indicate 1.3 6 0.3 Vdc When SAS SYSTEM YAW RATE Control Is Turned Fully Clockwise.

TM 1-6625-735-14

TABLE NO. 3-34. Multimeter No. 1 Does Not Indicate 12.0 6 0.5 Vdc And Multimeter No. 2 Does Not

Indicate 12.0 6 0.7 Vdc When AS SENSOR Switch Is Placed To SIM STAB 1&2. (Cont)

TEST OR INSPECTION

CORRECTIVE ACTION

6. Set AS SENSOR control counterclockwise until multimeter (No. 1) indicates 5.06

0.5 vdc. Multimeter (No. 2) shall indicate 5.0 6 0.7 vdc.

Step 1. If multimeter indication is not correct, replace circuit board assembly A1 and

retest.

Step 2. If trouble remains, replace circuit board assembly A2.

Step 3. If multimeter indication is correct, go to 7.

7. Place AS SENSOR control OFF. Go to 8.

8. Remove blue banana plug from AS SENSOR SIM NO. 1 test jack.

TABLE NO. 3-35. Multimeter No. 1 Does Not Indicate -1.3 6 0.3 VDC When SAS SYSTEM YAW

RATE Control Is Turned Fully Counterclockwise And Does Not Indicate 1.3 6 0.3 Vdc When SAS SYS-

TEM YAW RATE Control Is Turned Fully Clockwise.

TEST OR INSPECTION

CORRECTIVE ACTION

1. Connect multimeter (No. 1) between YAW RATE SIM (+) and SAS SIG REF YAW

(-) test jacks. Go to 2.

2. Place YAW RATE control to SIM 1. Go to 3.

3. Turn SAS SYSTEM YAW RATE control throughout its range from fully counter-

clockwise (L) to fully clockwise (R). Multimeter shall indicate -1.3 6 0.3 vdc when SAS

SYSTEM YAW RATE control is fully counterclockwise and shall indicate 1.3 6 0.3

vdc when SAS SYSTEM YAW RATE control is fully clockwise. 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 -1.6 to 1.6 vdc, replace poten-

tiometer R8.

4. Check switch S20 for continuity.

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

Step 2. If continuity does not exist, replace switch S20.
