8. Remove both front covers. Enter the diagnostic program, if necessary, per Procedure 3.2.
Using the diagnostic program allows to test the incline system without continuously
pedalling the unit. Connect a DC volt meter to the incline motor cable as follows: voltmeter
common lead to terminal 2 (brown wire) and voltmeter “hot” lead to terminal 3 (red wire).
Using the CROSSRAMP
, keys operate the incline. The voltmeter should read +12 Vdc
when the incline is instructed to move upward and -12 Vdc when the incline is instructed to
move downward.
9. If the voltage measurements in step 8 are correct replace the incline motor. If the either
voltage measurement in step 4 is significantly low, continue with step 10.
10. Verify that all of the wires in the intermediate cable (the cable inserted in to J3 of the lower
PCA) are securely inserted into the connector housing and providing a good electrical
connection.
11. If you have performed all of the above tests and are unable to resolve the problem, contact

12. Enter the diagnostic program per Procedure 3.2 and advance to the Lift Test. If the A/D
reading is either 0 or 255, skip to step 15.
13. Using the CROSSRAMP
, keys operate the incline. If the A/D reading tracks the incline
movement smoothly without skips, calibrate the incline motor per Procedure 5.3 and re-test
incline functions in a normal operating mode.
14. 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 and
between the intermediate cable.
15. 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 (green wire) and terminal 6 (brown wire) of the intermediate cable. The
ohmmeter should read approximately 1000Ω.
16. Test between terminal 4 (green wire) and terminal 5 (black wire) of the intermediate cable
and between terminal 5 (black wire) and terminal 6 (brown wire) of the intermediate cable.
These two readings should total approximately 1000Ω.
17. If the readings in steps 15 and 16 are correct, skip to step 19. If either reading is significantly
high or low, continue with step 18.
18. Disconnect the intermediate cable from the incline motor cable. Using an ohmmeter read
each of the six wires in the intermediate cable from end to end. Each of the wires in the
intermediate cable should read less than 1Ω. If any of the readings are significantly high,
replace the intermediate cable. If all of the readings are correct, continue with step 19.
19. Replace the incline motor. Calibrate the incline motor per Procedure 5.3.
