Sun psu in a Sega Blast City

[Wesinator]

Hi

Does anyone know which pink and blue wires in the blast city correspond with the black and white wires on the sun psu.

Thanks

Pink/blue is 100VAC, be careful but you should be able to pull that from any of them that have a thick enough gauge.

I'm confused though, the stock blast PSU will power a Naomi 2 GD setup by itself unless it's failing. Any reason you're opting for the Sun here?

Running a naomi with netdimm. It loads the game but as soon as it is about to run it switches to the test screen. I have a sun psu so I was thinking it could be a power supply issue so I would like to try the sun. Just need to know if the blue wire goes to the black or white on the sun psu and which one the pink wire goes to.

Have you checked the voltages coming out of the blast PSU with a multimeter? You can adjust both 3.3v and 5v, and as far as I know the Blast PSU should supply enough juice for a netdimm setup

Thanks I will test the psu voltages

In my experience, a Naomi 1 will exhibit this behavior in a Blast. Naomi 2 seems to run fine, for whatever reason though.
