Trouble Shooting the Weider Crossbow Platnium
MODEL: WESY78730
I would like to start off with the lower wire harness which seems to be most of the problems with this machine and what color wire goes where:
BLACK GROUND WIRE: first connects to the lowest weight limit switch located in the hinge part of the pivot arm or top of the arm, it then multiples down to the highest weight limit switch located at the other end of the pivot arm near the motor, then the black ground wire multiples to a terminal that connects to the resistance sensor located at the end of the pivot arm.
ORANGE WIRE: This is the wire that causes the most trouble it connects to the lowest weight limit switch located in the hinge part of the pivot arm or top of the arm.
WHITE WIRE: Connects to the highest weight limit switch located at the other end of the pivot arm near the motor.
BLUE AND YELLOW WIRES: Connect to the motor at the end or bottom of the pivot arm.
PURPLE WIRE: Connects to a terminal that connects to the resistance sensor located at the end of the pivot arm.
SYMPTOM AND POSSIBLE FIXES:
SYMPTOM: The weight will no longer ajust down to a lighter weight.
FIX: Check the Orange or BLACK wire leading to the low weight limit switch located inside of the hinge of the pivot arm. This will be on the right side of the machine looking from the back. The ORANGE wire may be cut, pinched or pulled out of the terminal as mine was. Splice a longer wire with another terminal on the end and reattach it to the switch.
You may need to remove the switch by running the motor by hand down to the lightest weight and then pulling the cable out and wrapping it around something and hooking it securely.
You will need a small philips head screw driver to get to the screws and a pair or neddle nose pliers to get the the nuts.
Make sure to unplug the machine.
SYMPTOM: The weight will not adjust to a heavier weight.
FIX: Check the WHITE or BLACK wire leading to the high weight limit switch located at the end of the pivot arm on the left side of the machine looking from the back. The wires may be cut,pinched or just worked loose from the terminal. Replace the wires or reconnect them to the switch.
SYMPTOM: When you try to adjust the weight you get something that says
“ Release the tension on the cables and set to desired weight”
And the weight readout jumps to 10, 100 or some other number.
FIX: Check the PURPLE or BLACK wire that connects to a terminal that goes to the tension sensor located at the end of the pivot arm or left side looking from the back of the machine. Both of these wires have been known just to fall out of the terminal.
The best fix for this is just to by pass the terminal and splice a wire from the PURPLE wire to the GRAY/BLACK wire and then splice another wire from the BLACK wire to the BLACK wire leading to the resistance sensor.
The best fix that lasts, is to do what I did and what others are doing and disconect the wires from the terminals that are going to the bottom or left side of the pivot arm to the motor, high weight limit switch and the tension sensor, cut the ties that hold them to the pivot arm and pull them out of the pivot hinge encloser that usually cuts or crimps these wires. You will then need to splice wires back to these wires in order to make them longer so that they can then be routed to the outside of the pivot arm hinge and away from the moving parts. Connect the wires back to the wires for the high weight limit switch,motor and sensor then wrap them good with tape a tie them back to the pivot arm using cable ties leaving enough slack for them to move freely outside of the pivot arm hinge and away from the moving parts. I also recomend bypassing the terminal that connects to the resistance sensor and connecting the PURPLE and BLACK wires directly going to the sensor. Now the only 2 wires that are inside of the pivot arm hinge are the ones that go to the Light weight limit switch which can not be avoided because that is where the switch is located.
Hope this helps because the machine is very good if it is working correctly.
It just had poor engineering when it came to the wiring.
