TM 1-6625-735-14

TABLE NO. 3-32. SAS SYSTEM AIRSPEED SWITCH ,60 KNOTS Indicator Does Not Go On When

LATL ACCLRM Control Is Set Above 1.3 Vdc And Does Not Go Off When LATL ACCLRM Control Is

Set Below 1.0 Vdc. (Cont)

TEST OR INSPECTION

CORRECTIVE ACTION

3. Place SAS SYSTEM AIRSPEED SWITCH to NORM. Go to 4.

4. Place LATL ACCLRM control to SIM SAS 1. Go to 5.

5. Turn LATL ACCLRM control counterclockwise (L) and clockwise (R) to vary

multimeter indicator 1.0 6 1.0 vdc. SAS AIRSPEED SWITCH ,60 KNOTS indicator

lamp shall light between 1.4 6 0.1 vdc and shall remain on above this voltage range;

also, SAS AIRSPEED SWITCH ,60 KNOTS indicator shall go off 1.1 6 0.1 vdc and

shall remain off below this voltage range.

Step 1. If multimeter indicates 0.0 vdc, go to 6.

Step 2. If multimeter indication is not correct, replace component board assembly A3.

6. Check switch S23 for continuity.

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

Step 2. If continuity does not exist, replace switch S23.

TEST OR INSPECTION

CORRECTIVE ACTION

NOTE

Test lamps for condition before continuing.

During the following steps, note the status

(on or off) of all lamps.

1. Place SAS SYSTEM AIRSPEED SWITCH TO >60 KNOTS. Go to 2.

2. Turn LATL ACCLRM control fully clockwise (R). SAS SYSTEM AIRSPEED ,60

KNOTS indicator lamp shall go on.
