Help with soldering power connector to PCB?
(1/2) > >>
DeLuSioNal29:
Hello all,

I recently inherited a Konami all in one consumer arcade unit.  However, one of the pins on the DC power connector on the circuit board broke off.  So I unsoldered it and I'm in the process of locating a replacement part.

However, I was thinking... Is there any reason why I can't cut the power cord end off and solder it directly to the board?  If so, what would go where?  There are 3 points on the circuitboard, but I'm assuming there are only 2 wires available to solder.

Any ideas?  Pics below for reference.  The last pic is of how the connector looks.

Thanks in advance for your help with this.

P.S. - Found this link, but not sure if it will work or not.

You should be able to solder it directly to the board without any issues that I can see. The only thing you need to worry about is to get the polarity correct (ie... + to + and - to -).

Yeah, but the trouble is I don't know what wire goes to where.  I wish I had the pinout of the connector.  There are 3 prongs.  Which is negative and which is positive?  And what's the 3rd prong for?

Generally speaking, the negative/ground pin would have attached to a trace on the PCB that runs pretty much everywhere on the board.  Should be easy enough to figure out with a multimeter/continuity tester.

Two of the three pins most likely both go to ground.  Only one pin would be positive.  Again, you should be able to confirm that with a continuity tester on the PCB, or the old jack.
