Memory Set LED Circuit

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 volts. Reversing the leads, the meter should read OL.

If the meter readings are not as indicated above, replace the switch; otherwise, return to the pinpoint test.
