4.5 Troubleshooting – 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.
