Memory Positioning Switch: Testing and Inspection

SWITCH - MEMORY SET

Memory Set Switch:

Remove the memory set switch.







Measure the resistance between the indicated terminals while pressing the requested switches.

The resistance should be less than 5 ohms for each switch position.







If the resistance is not less than 5 ohms for each switch, install a new switch; otherwise, return to the calling pinpoint test.

NOTE: Refer to multimeter user's manual for testing diodes.

To check the memory set switch LED, connect the positive meter lead to terminal 8 and the negative lead to terminal 9. The meter should indicate greater than 0.3 volts. Reversing the leads, the meter should read O L.

If the meter readings are not as indicated above, install a new switch; otherwise, return to the calling pinpoint test.
