How to replace the power cable on an N64 power supply.

Tools: Nintendo 64 security bit screwdriver; Lead-Free Solder; Soldering Iron; iFixit Precision Utility Knife; Small Chain Nose Pliers; Loctite Super Glue; cord with polarized plug; Coaxial Cable Crimper, Wire Stripper and Connectors; Power Drill

Step 1

• Unscrew the 2 security screws on the corners of the case using a 4.5mm security bit driver.

Step 2

• Remove the cover by gently prying from the side with the screws.
• NOTE: There are two clips that will let loose on the opposite side as you pry.
• NOTE: This will expose the circuit board needed for the repair.

Step 3

• Remove the circuit board from the other half of the plastic case by pulling it straight out
• NOTE: There may be some adhesive holding it on to the plastic

Step 4

• Remove the original power leads by melting the solder using a soldering gun.
• CAUTION: You will need to pull the wire from the backside but use caution to not touch any metallic parts as they will be hot.
• NOTE: If you do not know how to solder, read this Soldering Skills (https://www.ifixit.com/Device/Soldering) guide on ifixit.

Step 5

• Clear the boot by pulling the copper wires out with pliers.
• NOTE: This will leave the wire sheathing which can then be cut flush with sharp knife.
• NOTE: Tip: Sand cut the end with fine grit sandpaper if desired.

Step 6

• Use the drill to drill out the wire sheathing.
• Drill each hole twice.
• First, use a 5/64th drill bit. Then, use a larger 1/8th drill bit to finish.
• NOTE: The holes should be clean and free of debris once complete.

Step 7

• Feed the new cable through the boot .
• Glue it in place by applying glue to the wire (close to the desired location of the boot) and sliding the boot into place.
• NOTE: Be sure the exposed wire length is close to the original.

Step 8

• Align the wires with their original positions on the circuit board.
• Looking at the component side of the board, the hot side is marked with an L for load and the neutral is marked with an N.
• The neutral wire goes here, the hole closer to the center of the circuit board.
• The hot wire goes here, closer to the outside.
• NOTE: The neutral wire can be identified by the wider prong on the plug end of the cord.

Step 9

• Solder the new wires onto the circuit board.

Step 10

• Use a flexible glue to put on the original adhesive.
• Insert the board, aligning the boot with the slot.

Conclusion

To reassemble your device, follow steps 1-3 in reverse order.
