Step 5Testing Part 1
No matter how good you are, or how certain your work, you always want to test early and often. If there are any failures in the soldering, it is much easier to correct now, before the large cable is in our way.
We will be doing continuity tests. If you're multimeter doesnt have a function for checking continuity, set it for checking resistances at its lowest setting. Just remember that infinite resistance means no connection, and almost no resistance means connected.
First, check the lines ties Low. For our Button Select USB example, that would be pins 3-7 and 15. Place one probe on pin 1 (GND). Take the other probe and check pins 3-7 in order. Each one should show almost no resistance to pin 1. Check the last Low pin, 15. All of the pins tested should be connected to pin 1, and show almost no resistance.
Repeat for the High lines. For our Button Select USB example, that would be pins 10, 11, and 2. Place one probe tip on pin 8 (VCC), and check the continuity with pins 10, 11, and 2. Each should show almost no resistance.
Lastly, check for shorts. Place one probe on pin 1, and the other on pin 8. There should be NO continuity. Infinite resistance. If these two lines are electrically connected, there is a short somewhere in your work. You MUST fix these before ever trying to use the cable. Using a shorted cable on a console may blow fuses, may cause fires, may fry your console and stick. It's bad, so fix it NOW.
If everything test correct, let's start work on the console cable.
