CHAPTER 4: TROUBLESHOOTING
4.2 Troubleshooting – No Display on the Console or the Display is Dim
NO DISPLAY ON THE CONSOLE OR THE DISPLAY IS DIM
POSSIBLE CAUSES:
1. The console is damaged or the console cable is not connected properly.
2. Poor connection to all the terminals on the lower control board.
3. The lower control board is damaged.
4. The generator is damaged.
SOLUTION:
1. Check the connection of the console cable at the UCB.
2. Remove the console cable from the JHD socket on the console. Pedal the machine and set your multi-meter to DC voltage and place both
terminals on pins 1 & 7 of the console cable. There should be a reading of more than 5.5VDC (Figure A).
- If voltage is more than 5.5VDC, replace the console.
- If voltage is less than 5.5VDC, or the new console does not resolve the issue, replace the console cable.
3. Open the shrouds then check if all the wire harnesses are connected properly to the terminals of the LCB.
4. Unplug the generator cable from the control board, pedal the machine and set your multi-meter to AC voltage and place both terminals on pins 1 &
2, pins 2 & 3, and pins 3 & 1 of the console cable to check if the voltage is variable (Figure B).
- If the voltage reading shown is variable (varies based on RPM), replace the LCB.
- If the voltage reading shown is not variable, replace the generator.

CHAPTER 4: TROUBLESHOOTING
4.3 Troubleshooting – No RPM is Displayed During the Exercise
NO RPM IS DISPLAYED DURING THE EXERCISE
POSSIBLE CAUSES:
1. The console is damaged or the console cable is not connected properly.
2. Poor connection to all the terminals on the lower control board.
3. The lower control board is damaged.
4. The generator is damaged.
SOLUTION:
1. Check the connection of the console cable at the UCB.
2. Remove the console cable from the J5 socket on the console. Pedal the machine and set your multi-meter to resistance and place a terminal on pin
3 of the console cable at both the LCB and UCB. There should be a resistance (ohm) reading (Figures A & B).
- If a resistance reading is shown, replace the console.
- If the there is no resistance reading, or a new console does not resolve the issue, replace the console cable.
3. Open the shrouds and check if all the wire harnesses are connected properly to the terminals of the LCB.
4. Unplug the generator cable from the LCB and pedal the machine to check if the voltage is variable.
- If a variable voltage reading is shown (varies based on RPM), replace the LCB.
- If the voltage reading shown is not variable, replace the generator.

CHAPTER 4: TROUBLESHOOTING
4.4 Troubleshooting – All or Some of the Function Keys Do Not Respond
ALL OR SOME OF THE FUNCTION KEYS DO NOT RESPOND
POSSIBLE CAUSES:
1) The keypad connection ribbon cable has not been plugged in correctly.
2) The keypad is damaged.
3) The UCB is damaged.
SOLUTION:
1) Check the connections of the keypad at the UCB.
a. Remove the console from the console mast.
b. Remove the 4 screws holding the back of the console to the front (Figure A).
c. Inspect the keypad ribbon cable connection at the UCB (Figure B).
d. Even if the keypad ribbon cable appears to be connected correctly, unplug and reseat the cable, then retest.
2) Replace the affected keypad.
3) Replace the UCB.

CHAPTER 4: TROUBLESHOOTING
4.5 Troubleshooting – High or No Resistance
HIGH OR NO RESISTANCE
POSSIBLE CAUSES:
1) The console is damaged or the console cable is not connected properly.
2) The console cable is damaged.
3) The power resistor is damaged.
4) The LCB is damaged.
5) The generator is damaged.
SOLUTION:
1) Check the console cable connections at the UCB and LCB.
2) Remove the rear shrouds and check if the console cable is connected properly to the LCB.
3) Set your multi-meter to resistance (ohms) and place both terminals on the power resistor wires .Check the power resistor wires for resistance (Figure
A).
-If the power resistor wire does not have resistance, replace the power resistor.
4) Unplug the generator cable from the LCB. Pedal the machine and set your multi-meter to AC voltage and place both terminals on pins 1 & 2, pins 2 &
3, and pins 3 & 1 of the console cable to check if the voltage is variable (Figure B).
- If a variable voltage reading is shown (varies based on RPM), replace the LCB.
- If the voltage reading shown is not variable, replace the generator.

CHAPTER 4: TROUBLESHOOTING
4.6 Troubleshooting – Pedals Slipping
PEDALS SLIPPING
POSSIBLE CAUSES:
1) The belt tension is not high enough.
2) The one way bearing is damaged.
SOLUTION:
1) Remove the shrouds and check the belt tension.
a. Tighten the drive belt tension if needed by moving the spring tension clip to another hole.
b. The generator belt should be tightened to 85 ft / lbs.
2) If the belts are tensioned correctly, the one way bearing is damaged, replace the drive assembly.
4.7 TROUBLESHOOTING – KNOCKING OR CREAKING NOISE
KNOCKING OR CREAKING NOISE
POSSIBLE CAUSES:
1) There is hardware that is not tight or is missing.
2) The noise is related to the incline.
3) The belt tension is not high enough, or the belts are too dirty.
SOLUTION:
1) Inspect the unit and check for any loose hardware. Pay special attention to areas where arms meet. Tighten hardware where found.
2) If the noise is present only during incline, check to make sure the Teflon washers are installed at the incline motor connection point (Figure A).
a. Lubricate the gear shaft of the incline motor with grease (Vision recommends Super Lube brand Lithium Grease where available).
3) Remove the covers and check the belt tension.
a. Tighten the drive belt tension if needed by moving the spring tension clip to another hole (see Section 5.17). It should be set to 180 ft / lbs of
tension.
b. The generator belt should be tightened to 90 ft / lbs.
4) Clean the belts. If they are worn or will not clean, replace the belts.

CHAPTER 4: TROUBLESHOOTING
4.8 Troubleshooting – Heart Rate Function Does Not Work or is Reading Incorrectly
HEART RATE FUNCTION DOES NOT WORK OR IS READING INCORRECTLY
POSSIBLE CAUSES:
1) The heart rate grips are not connected properly or are defective.
2) The heart rate grip wiring is damaged or not connected correctly.
3) The HR board is damaged.
4) The UCB is damaged.
SOLUTION:
1) With a multi-meter set for DC voltage, place one terminal on each of the HR grip plates. The HR grip should give a voltage reading of between 0.5 and
2.0VDC.
a. If the voltage is not between 0.5 and 2.0VDC, remove the 3 screws holding the HR grip together and check the connection of the HR grip wiring.
2) Check continuity of the HR grip wiring.
a. Place one terminal of a multi-meter set for resistance on the HR grip wiring at the HR grip, and the other terminal on the HR grip wiring at the
console. An ohm reading of around 1 should be expected. If the reading is higher than 1, replace the HR grip wiring.
3) Remove the console. Remove the 6 screws holding the front of the console to the rear. Check the connection of the HR board wiring to the UCB.
a. If all the wiring is intact and has good contact, replace the HR board.
4) If the HR board, HR grips, and HR grip wiring do not solve the issue, replace the UCB.
