3. Attach the solenoid wires to the color change PCB on head #4 or the thread
break harness connection on the other embroidery heads.
Note: The two wires coming from the solenoid body and connecting at the small
black plastic connector, can be damaged if they are twisted together.
Twisting the wires together will reduce their length and can put undue
stress at the connections at both ends. We therefore do not recommend
twisting these wires together. If you must group these wires together,
use "cable ties" (plastic straps) these are available at most electronic
supply stores.
4. Reinstall all covers removed to change the jump stitch solenoid and test
embroider a large letter (6 inch block I, for example) to check the machine for
proper jump stitch operation.
Color Change Motor Belt Tension
The color change belt tension should cause the color change cam to rotate with
minimum backlash. The belt should be tensioned with some amount of slack so it is
not so tight that it wears the color change shaft and bushings needlessly.
Adjust the color change belt tension by loosening the color change motor
mounting screws and moving the motor to make the belt more or less taut. When
tightening the belt tension, use hand pressure only on the motor. No additional
force is needed.
