How to know if 32x is powered on without video

[goodtofufriday]

Hey all. Im doing a psu mod and right now and the psu im using is rated at 12v 4A

I supposed that it would be enough to power a model 1, cd model 2, and a 32x.

The pus powers the gene and cd just fine but adding the 32x gives me no power across the board. I assume there just isn't enough amperage getting through.
I revered the wiring on my home made cable and then everything turns on, but im pretty sure it's just because now the 32x has the power lines revered and now gets no power. But im asking here just to be sure.

So is there anyway to tell if the 32x is actually getting powered on without video?

I currently dont have an adapter cable for a model 1 genesis. Ill be making one soon. In the mean, any way to tell?

You have a Model 1, get some headphones and listen for the game... Or just plug the Genesis AV out into the TV. With most 32X games you'll get some graphics on the Genesis, but not everything.

About power though, remember that the 32X uses a center-positive polarity for its DC jack. Genesis Model 1 and SCD Model 2 are center-negative. Look at a polarity diagram on a PSU, you'll see what I mean.

Also, when you build your custom 32X cable, do not connect +5v, or the Genesis 32X won't turn off when you flip the power switch.

Thanks! I'll try pluging it to a screen soon as a game comes in the mail.

I had no clue the 32x was center positive. That must be my problem. Just assumed it was all center negative. Solid info there.
