Switch - Memory Set
MEMORY SET SWITCH
Remove the memory set switch.
Measure the resistance between the following indicated terminals while pressing the requested switches.
TESTING MEMORY SET SWITCH
| Switch | Terminals |
|---|---|
| Memory Switch 1 | 6 and 4 |
| Memory Switch 2 | 6 and 3 |
| Memory Set Switch | 6 and 1 |
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.
TESTING MEMORY SWITCH LED
| Switch | Terminals |
|---|---|
| Memory Switch LED | 8 and 9 |
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 volt. Reversing the leads, the meter should read OL.
If the meter readings are not as indicated above, install a new switch; otherwise, return to the calling pinpoint test.
