Title: How wire this Power Supply?
Post by: savj14 on March 28, 2020, 05:48:41 pm
I have a Jamma PCB that I'm looking to test and possibly sell but I wasn't sure how to wire up and test the Power Supply in the attached pics. I have no idea if it even works but I figured I'd test it and if all else fails I'll buy a new one. I have a power cord stripped with green, white, and black wires but I wanted to ask here before I do anything.

Black and white to AC110 (doesn't matter which since it is not labeled on the PS)
Green to FG

Thats it

Awesome thanks for the quick reply back. Would the Ground from the Jamma connector go to FG as well?

What is the 0V connection use for?

What should I use for testing the Voltage? I've tried the different VDC options and none of them will show close to 5 volts.

0V is where you should hook up jamma ground.

You probably won't get a good reading without a load.

The Power Supply has an adjustment nob on it. If I have a PCB connected with the voltage too high so I can test and get a reading is there any chance I can ruin the PCB?

Turn it all the way widdershins before you plug a pcb into it.  Adjust as necessary.

Haha I had to Google that one as I thought it was a typo or something. You really do learn something new everyday I guess.

Thanks for the info and I'll give that a go tomorrow. I'll give it the old "Lefty Loosey"

I noticed the adjustment knob is missing.  How will you be turning the knob?
