im giving this n64p tyhing one more try before i give up on the 3 power circuit crap and fall back on my DS. does ANYBODY know which of 6 lines connect to each other>? my multitester is new and it says they all short. so, help! please!

Ok now say that in a way we can understand.

WHICH 6 Wires?

the 6 power wires going into the n64.

Here's something from daguuy's site:

yup. you can see the traces connecting them on the bottom of the PCB and they're labeled. here's a newer better pic:

ok when i hook up 12v+ and the two 3.3v+, then i touch the 12v- to each of the three gorund wires in turn, they spark slightly which means NOT GOOd. waht am i doign wrong?

you only need to connect to 1 3.3v pin and 1 ground. make sure the're good connections and nothing's bridging

negative 12v? you just mean the negative side of a 12v source right? 24v would be severly unnsecary...

anyhow, sometimes things spark when you plug them in. it just takes a high initial current to charge up all the caps and such. kettles will spark if you unplug them real fast. that has to do with inductance though...

anyhow, it could just be that. unless you feel that these sparks are way to big to be normal or something. i suggest learning how to use a multimeter before you do anything else. if the power lines really are shorted youre going to hurt your batteries.

ok, sorry if im annoying you guys, but i need to make sure im not making a mistake before i assume my n64 fried and go get another one (keep in mind I don't have an adaptor to test)

heres my set up so far...

i need to know which of those 6 wires (2/12v-4/3.3v) go to which power holes (1-6) as seen here.

ok i don't think you really understand this so here's how it works:

you have +12v , +3.3v, and ground (0v, not negative 12 or 3.3 volts). you only need 1 wire for 12v, 1 wire for 3.3v, and 1 wire for ground. ground can go aywhere on the board that's connect to the thick strip of metal around the outside of the mobo (pin 1, 5, or 4 will work). your 12v wire goes to the pin connected to the thread labeled "12v" (pin 6), and your 3.3v wire goes to any of the pins connected to the thread with the "3.3v" label on it (pin 2 or 3). even though there's 6 pins, you only need to connect 3 wires

thank you for clearing that up, sir.

your welcome, glad i could help

IBUS · Post by **IBUS** » Mon Jan 30, 2006 8:42 pm

so the final wiring might look like this?

IBUS · Post by **IBUS** » Mon Jan 30, 2006 8:47 pm

wait...are you talking about what the wiring will look like AFTER putting it through a screen? because i'm not using the PS1 screen im using a 6.8 inch madcatz lcd.

daguuy · Post by **daguuy** » Mon Jan 30, 2006 9:02 pm

no i wasn't talking about the screen at all, just powering the N64. i'm not sure what the thing sticking up on the right of your pic is but you got the 3.3v and 12v right. however, one of your grounds is connected to a 3.3v pin instead of ground (the one connect to a middle pin), just keep your ground to the right and you only need to connect it to 1 pin
