Problem Arcade Power Supply to a 24pin power input Supergun.

No, man. Yellow should be +12V. Blue is -12V (negative 12V).

Yup, just saw it, I messed up, going to fix it asap.

You didn't mess up big time, so don't worry. That blue cable for -12V most likely isn't routed to the edge connector.

Yup, that's why I had to get that bodge wire, I saw the positions wrong on the 12v, missed the -, fixed and now working as intended, thanks a lot for the heads up mate!!

A newbie question for you more expert people, can I adjust the voltage while the power is on?

 

[Lurch666]

You can.
But be aware that adjusting it too high could damage the PCB.
I have a cheap little LED voltage indicator attached to the +5V line so I can always see the voltage output.

I have one arriving today! Just solder it to the ground and one of the 5v pins on the edge connector right Lurch? Thanks a lot!

Yup. Then use your multimeter to adjust the trim pot in the back to the correct voltage.

Always turn the voltage back down again when swapping boards and recalibrate from there.
Just because it's set at 5v for one board won't mean it'll be 5v for the next one as the power draw will be different

Thanks for the heads up! Toki is really one of the hungriest I have, damn ape likes volts.

Update: Power hungry Toki with it's new voltmeter!


Can I ghetto a light fixture switch thing to the power cable so I can turn it on and off?

 

[channel27]

Yes, you can put a switch inline on the AC cable. That's exactly what's happening in a cabinet that has a on/off switch.

On the way! Thank you!
