Got my shiny new MCR Switcher adapter from Arcadeshop yesterday, and got around to hooking it up today. I did not purchase one of their power supplies, but I was told one I pulled out of an old computer could work, and the specs seem nearly the same. Just for reference, here are the specs of the PS I wired to the adapter:
115/230V selectable, 250W, +5V @ 25amps, +12V@ 10 amps. The supply also has -5 and -12 both at .5 amps.
So here comes the fun part: after wiring up the adapter, I set the PS in the cab and for testing purposes plugged the PS into the outlet in the bottom of the cab. I know I should not leave the PS like this, but the PS has a switch on it so it did not automatically cut on. I figure this was fine for quick testing purposes before I hardwired the PS into AC.
After plugging in the cab and turning on the PS, smoke started coming from the end of the board with the big power connector and one of my brand new (ARG, not like I have any more of these just laying around >_< ) ribbon cables burnt straight through.
The switcher adapter, however, did not smoke, and looks unharmed, so I'm thinking the issue is not with my power supply or switcher adapter.
I am also pretty sure I did not have the power connector or ribbon cables plugged in backwards, I quadruple checked them to make sure.
I still have the iso trans wired up, after disconnecting the PCB the monitor, marquee, and other lights still turn on.
Now I'm scared to turn the damn game on with the board connected again, not to mention I'm missing one ribbon cable. Any idea of what could have happened/what I can do to fix this would be awesome, thanks in advance.
