Component Tests and General Diagnostics
SWITCH - MEMORY SETMemory 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.
