MALFUNCTION

TEST OR INSPECTION

CORRECTIVE ACTION

(7). Connect a TS-352/U multimeter or equivalent in the 2-5 amp range, across jacks N of breakout

box and open switch N.

(8). Energize the system in the BIAS mode and observe the multimeter. If the solenoid switch is

adjusted properly, the current should be 0.05 amp. If the solenoid draws 1.5 amps, the switch

must be moved closer to the solenoid. Should the solenoid chatter and draw high current, then

the switch must be moved away from the solenoid.

(9) Switch from BIAS to SELF-TEST several times to insure proper operation.

Adjust the caging cam switch as follows (fig. 2-80).

(10). With the caging link adjusted, set up the system for operation and energize the caging

mechanism by placing the MODE SELECT SWITCH in the BIAS mode. Manually hold the

clutch in the engaged position so that it is not released while adjusting the caging arm switch.

(11). Loosen the caging cam switch mounting screws. Adjust the caging cam switch so that the

actuator solder follows the depression on the cam and is actuated when the caging arm guide pin

is 1/32 inch from the top of its guide slot (fig. 2-80).
