Follow the step-by-step guide to properly diagnose the error. Pay special attention to those tests
indicated in numbered boxes, and described in detail here below:
(1) Insert the multimeter probes between pins 1 (signal) 4 of the connector on the photocell board.
You should get a reading of approximately 5 Vdc.
(2) Insert the oscilloscope probes between pins 2 (signal) and 4 of the connector on the photocell
board. With the motor enabled you should see a square wave signal ranging from
approximately 0 Vdc to 5 Vdc.
