LED Cluster Harness
There are two led cluster harnesses connecting the LED cluster assemblies to the Main PCB at locations
“Light 1/2” and “Light 3/4”. The led cluster harnesses will rarely require replacement at the same time.
The usual cause for replacement of either harnesses will likely be due to damage caused in handling the
harnesses during repairs and/or maintenance procedures.
Replacement Parts Needed:
• harness, LED cluster
• twist-lock cable ties (available at most hardware stores in the electrical section)
Replacement Procedures:
Left LED Cluster Harness:
1. Turn the machine ON.
2. Color change to Needle 16.
3. Turn the machine OFF.
•
CAUTION!! Use extreme care not to drop metallic objects, tools, or other conductive material
on the Main PCB when you have the base cover removed. If you drop such objects on the Main
PCB, it can severely damage the electronics which will be very expensive to repair.
4. Remove the left upper arm front cover, the right arm cover, and the base cover.

5. Disconnect the LED cluster harness from the left LED cluster assembly.
6. From the back side of the left upper arm, pull the harness through the access hole located just
above the x-cable tensioning bracket (Figure 1).
