TABLE NO. 3-33. SAS SYSTEM AIRSPEED SWITCH >60 KNOTS Indicator Does Not Go On When

LATL ACCLRM Control Is Fully Clockwise And SAS SYSTEM AIRSPEED SWITCH ,60 KNOTS

Does Not Go On When LATL ACCLRM Control Is Fully Counterclockwise. (Cont)

TEST OR INSPECTION

CORRECTIVE ACTION

3. Place SAS SYSTEM AIRSPEED SWITCH TO ,60 KNOTS. Go to 4.

4. Turn LATL ACCLRM control fully counterclockwise (L). Indicator lamp SAS

SYSTEM AIRSPEED ,60 KNOTS shall go on.

Step 1. If indicator lamp does not go on, replace switch S23.

Step 2. If indicator lamp goes on, go to 5.

5. Place SAS SYSTEM AIRSPEED SWITCH to NORM. Go to 6.

6. Remove yellow banana plug from test set.

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.

TEST OR INSPECTION

CORRECTIVE ACTION

1. Connect blue banana plug of locally-made cable to AS SENSOR SIM NO. 1 test

jack. Go to 2.

2. Connect multimeter (No. 1) between AS SENSOR SIM NO. 1 and SIG GND test

jacks. Go to 3.

3. Connect multimeter (No. 2) between SAS SIG REF PITCH and SIG GND test jacks.

Go to 4.

4. Place AS SENSOR control to SIM STAB 1&2. Go to 5.

5. Set AS SENSOR control to a multimeter (No. 1) indication 12.0 6 0.5 vdc. Multi-

meter (No. 2) shall indicate 12.0 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 6.
