Upon starting any bike program, if the screen will not
advance, asks if you would like to end workout, RPM
signal is not being detected at the upper console, check
the following:
1. Starting from the console assembly check to make sure
the console data cable is plugged in firmly to the console
and into the lower board and check for
disconnections/cable damage in the pedestal neck.
2. If damage is found and cable has no continuity replace
cable. If cable tests good with a meter proceed to the next
step.
3. Check to make sure there is AC voltage at the lower board
from all three phases from the generator. The white cable
on the generator cable carries the RPM voltage.
4. If there is no AC voltage on the white cable check the
continuity of the cable. If there is no continuity replace the
generator cable. If there is continuity proceed to the next
step.
5. Check the voltage across all three phases of the generator.
If there is not voltage when the generator is moving across
all three phases replace the generator. If there is voltage
across 3 phases replace lower board.

No Resistance
1. Leaving the console cable plugged into the upper console,
probe the console cable on pin 9 (Control Out) and pin 4 (GND)
for Volts DC. Press the workload up button (+) on the upper
console. Voltage should increase as resistance increases.
Check for same at the lower board also. (If there is voltage at
the upper and not the lower board replace the data cable)
2. If the voltage does not increase, replace the upper console.
3. If the voltage increases, check the coil cable for Volts DC on the
lower board, with the cable connected to the controller. Dig
through the glue and probe both cables. Voltage should
increase as resistance is increased.
4. If there is no increase in voltage at the controller, replace the
controller.
5. If there is a voltage increase at the controller, probe the coil
cable connector at the base of the generator for DC Volts.
Voltage should increase as resistance command increases.
Note: You must leave the coil cable connected and probe the
back of the connector to get an accurate reading.
6. If there is no voltage increase at the coil cable connector,
replace the coil cable.
7. If there is voltage increase at the coil cable connector, replace
the generator assembly.

The touch screen console requires a DC power supply to
operate. follow the steps below to determine the component
issue.
1. Disconnect the 2 conductor power cable (red and black) at the
upper board and probe for 12 VDC
2. If you test 12 VDC at the upper, replace the console.
3. If there is not 12 VDC at the upper probe for 12 VDC at the
power supply under shroud.
4. If there is 12 VDC at the power supply replace the intermediate
power cable.
5. If there is no 12 VDC, check for 120 VAC coming in to the
power supply. If there is 120 VAC replace the power supply.

1. Disconnect the console cable from the upper console.
2. Check for 12 VDC on pins 1 (+12V), and 4 (GND), and check for
12 VDC on pins 2 (+12V), and 4 (GND). 11 &12= 12v, 9 & 10=

3. If 12 VDC is found across both pins, replace the upper console.
4. If 12 VDC is not found, check for continuity on the console cable.
5. If there is no continuity, replace the console cable.
6. If there is continuity on the console cable, locate the VCON LED
and GEN+ LED on controller.
7. If GEN+ LED is illuminated when pedaling and the VCON LED is
not lit, replace the controller.
8. If GEN + LED is not illuminated, check for Volts AC from the
generator cable (black and white wires) connected to J1 on the
controller. The reading should be approximately 50-80 Volts AC
at slow speed.
