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 rear 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.
