Troubleshooting The Interconnect Cable - Precor AMT Series Service Manual

9 If the voltage measurements in step 5 are correct and the motor does
not move replace the incline motor. If the either voltage
measurement in step 5 is significantly low, replace the motor.
10 If you have performed all of the above tests and are unable to
resolve the problem, contact Precor customer support
11 Enter the diagnostic program per
Accessing the P30 Diagnostic Software
STRIDE HEIGHT. If the A/D reading is either 0 or 255, skip to step
15.
12 Using the STRIDE HEIGHT , keys operate the incline. If the A/D
reading tracks the incline movement smoothly without skips,
calibrate the incline motor per,
137) and re-test incline functions in a normal operating mode.
13 If the A/D reading was erratic and did not smoothly follow incline
motion, visually check the connections between the intermediate
cable and the J3 connector on the lower PCA.
14
Exit the diagnostics program, and leave the unit idle long enough
for it to "shut off". Disconnect the red battery lead from terminal
M6 of the lower PCA. Remove the intermediate cable from the J3
connector of the lower PCA. Using an ohmmeter, test between terminal
4 (brown wire) and terminal 6 (orange wire) of the cable. The
ohmmeter should read approximately 1000 ohms (+/- 20 percent).
15 Test between terminal 4 (brown wire) and terminal 5 (blue wire) of
the intermediate cable and between terminal 5 (blue wire) and
terminal 6 (orange wire) of the intermediate cable. These two
readings should total approximately 1000 ohms (+/- 20 percent).
16 If the readings in steps 14 and 15 are significantly high or low,
replace the incline motor. Calibrate the incline motor per,
Calibrating the Incline Motor
