GameCube Mobo or power regulator broken?

[Elemental]

So I set out to making a GameCube portable, and I'm at a stage where I have everything out of the gamecube... And I wanted to test it, so I hooked it up to my tv, and turned it on, but nothing happened. The fan still turns on when it's connected to the power button thing, but even though I have the regulator board plugged into the mobo, it's not giving the mobo power? I plugged in the controller ports so I could see if the led lit up so I could see if it was maybe just a problem with the AV cable, but the led did not light up. I tried getting my multimeter and just like... Putting it on a bunch of pins randomly of the part of the regulator that plugs in because I couldn't find any clear enough guides of how to test for the output thing... But yeah. I don't know very much. This is confusing. Please help.

Whoa dude, step back for a min. Not a good idea to just poke about if you don't know what is what. But in kasars gcp guide the is a pinout of the regulator board. Start with that. I think there is one in Ashen's trimming guide as well. The fan will come on cause its part of the circuit before the regs. If you need help feel free to pm me I might not get back to you right away but I'll help when I can.
