TurboGrafx-16 Composite Cable – Step 3
Step 3: Attaching the Ground
Crank the soldering iron up a tad, around 35 – 40.
In this step we’re going to attach our spare piece of wire to the ground, and get a few heat shrinks in place.
Grab a 1/4″ heat shrink and cut its length in half. Slip it over the 3 signal wires and the copper stub of grounding wire. We’re going to try to cover the area where the grounding wire is coming from each of the 3 signal wires. Put it into position making sure to keep the 1/2″ of ground exposed, and try to slip it over the existing casing as much as possible. When in place, use a light to shrink the tube. Expose all sides of the heat shrink to flame and don’t hold the flame in any one spot. This should do a pretty good job of covering the area where the ground meets the signal wire.
Now grab the spare wire. In the last step we stripped 1/2″ of casing off one side and 1/4″ off the other. Right now we’re working with the 1/2″ end. We need to twist this around the 1/2″ of exposed ground. With the wires well connected, it’s time for our one solder joint. With the two wires soldered, we’re going to grab another heat shrink, this time a 1/8″ tube. Slip this over the spare wire and make sure it covers the area where the 2 wires are soldered. It needs to be completely covered, because this part will be exposed.
If any wire down in this area is still exposed, slip another 1/4″ piece over all 4 wires. Trim it to where it just does fit over any exposed wires at the junction of all 4 wires; we don’t want any excess tubing because this will begin to shorten the distance between wires and it may not fit on the console.
Finally, we need to add the pin connectors.
