Test pins from PC power supply
Today I faced with a “strange” problem, where I had to make some measuring on a car ECU motherboard. There were some pins very close to each other and a crocodile clips would may be shorten the pins, so I thought a while and got an idea. I disassembled an old PC power supply and found what I needed.
Check my photos how you can get a nice and safe for working wires from an old PC ATX power supply:
This is the motherboard power connector from the PC power supply unit, this is what we need.
Use a screw driver and push it into the connector from where you wish to push out the wire which you wish to use. Push the screw driver between the plastic and the metal pin. After that rotate the screw driver and slightly pull out the wire as in the next picture.
Rotate the screw driver right – left, if the wire won’t go out then push the screw driver into the opposite side. Repeat his on all four sides, until the wire jump out.
Ok, this is how it’s looks like when all of the wires are out.
Put some heat shrinking tube to the metal connector and shrink them to a safe size. So you got an insulated safe connector.
This is how it looks like after finishing.
You can also solder some needles or whatever you need and make your measuring or apply some signal to the test point or whatever you need it…
I know, this is not a big deal, but save some time and money if you have an old unusable PC power supply around your shop and make nice connectors…
I hope you enjoy this tutorial and will save lot of repair time.
