Remove the F1 fuse (6.3 amps) from the lower PCA. See Diagram 6.4.
Check the fuses resistance using an ohmmeter. The fuse should read 1
ohm or less. If the reading is significantly high, replace the fuse.
If the fuse is good or replacing the fuse does not correct the
problem, continue with step 5.

Enter the diagnostic program per procedure,
P80 Settings
(on page 51)
or
Accessing the P30 Diagnostic Software
(on page 13). Using the
diagnostic program allows you to test the incline system without
continuously pedaling the unit if you have an external power supply.
Otherwise, you will need to continue to pedal the unit. Connect a DC
volt meter to the J3 connector on the lower PCA as follows:
voltmeter common lead to terminal 3 (black wire) and voltmeter "hot"
lead to terminal 2 (red wire). Using the
STRIDE HEIGHT

keys
operate the incline. The voltmeter should read +12 Vdc approximately
when the incline is instructed to move upward and -12 Vdc
approximately when the incline is instructed to move downward.

If when the STRIDE HEIGHT keys are pressed, the display does not
indicate that the incline is moving or the A/D numbers are not
changing, troubleshoot the upper PCA and keypad per procedure
P80

(on page 106), or
P30 Troubleshooting
(on page 41) .

If the voltage measurements in step 5 are correct continue with step
8. If the either voltage measurement in step 5 is significantly low,
replace the battery.

If voltage is significantly low, verify that all of the wires in the
cable inserted in to J3 of the lower PCA are securely inserted into
the connector housing and providing a good electrical connection.
