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) and 2 of the CN10 connector on the Bio
servo board. You should get a reading of approximately 24 Vdc.
(2) Insert the multimeter probes between pins 17 (signal) and 1 of the K4 connector on the CPU
board. With the solenoid enabled (additional weight not selected) you should get a reading of
approximately 4 Vdc, while with the solenoid disabled (additional weight selected) you
should get a reading of approximately 0 Vdc.
(3) Insert the multimeter probes between pins 13 (signal) and 1 of the CN7 connector on the Bio
servo board. With the solenoid enabled (additional weight not selected) you should get a
reading of approximately 4 Vdc, while with the solenoid disabled (additional weight selected)
you should get a reading of approximately 0 Vdc.
On Chest Press and Leg Press, the BS-6/2 cable is divided into 2 parts through the
connector CN36. Carry out the test on this connector and, if necessary, replace only the
defective section of the BS-6/2 cable.
(4) Insert the multimeter probes between pins 5 (signal) and 6 of the CN3 connector on the Bio
servo board. With the solenoid enabled (additional weight not selected) you should get a
reading of approximately 24 Vdc, while with the solenoid disabled (additional weight
selected) you should get a reading of approximately 0 Vdc.
(5) Insert the multimeter probes between pins 3 (signal) and 4 of the CN24 patch cord. With the
solenoid enabled (additional weight not selected) you should get a reading of approximately
24 Vdc, while with the solenoid disabled (additional weight selected) you should get a reading
of approximately 0 Vdc.
(6) Insert the multimeter probes between pins 3 (signal) and 4 of the CN26 patch cord. With the
solenoid enabled (additional weight not selected) you should get a reading of approximately
24 Vdc, while with the solenoid disabled (additional weight selected) you should get a reading
of approximately 0 Vdc.
