Bowflex LateralX LX5 Service Manual page 31

To get access to the Lower Wiring Harness, remove the Right Upper Shroud from the main body of the machine. (Refer to the "Replace the
Lower Data Cable" procedure in the LX3 or LX5 Service Manual.)
h. Check Lower Wiring Harness
• Remove the Right Upper Shroud and disconnect two wiring connections.
• Locate 12 pin plug coming from main body of machine.
• Locate Purple and Pink Wires (see image).
• Set DMM to measure DC voltage.
• Connect positive probe to Pink Wire Pin 2.
• Connect negative probe to Purple Wire Pin 1.
• Voltage should be within 11-13VDC.
- If no voltage is present, there is a break in Lower Wire Harness or power plug. Inspect and replace as necessary.
- If voltage is present but test at console failed, then fault is isolated to the Wiring Harness in the Mast Assembly. Re-seat all connec-
tors and re-check power to console (Step 2 above). If issue persists then replace the Wiring Harness in the Mast Assembly.
WORKOUT PAUSES WHILE PEDALING
If workout pauses while using the machine, then console is not receiving a signal from the tach Sensors. The sensor are reed switches that close
For these tests, set DMM to "Continuity" mode. This will typically have a symbol that looks like a sound wave and may be
combined with a Diode symbol or Ohms symbol. Make sure DMM is turned on, and test by touching the probes together.
Tester should emit a tone indicating continuity when the probes touch each other.
1. Disconnect power cord from machine and store in a safe place. Power is not required for these tests.
2. Check that signal is reaching the console. Remove mast cap and pull out the wiring harness. Disconnect four wiring connections.
A. Locate 12 Pin Plug coming from Mast Assembly.
B. Locate Yellow and Blue Wires (tach sensor 1, see image).
C. Verify DMM is set to measure continuity.
D. Connect one probe to Yellow Wire Pin 9.
E. Connect the other probe to Blue Wire Pin 8.
b. If beep is heard then connector was not secure or there is a break in the Upper Wiring Harness within the console housing. Remove back of
console to inspect and reseat wire, or replace if damaged.
