Power Connected, Doesn't Work

XFactor · Post by **XFactor** » Mon Apr 10, 2006 12:07 pm

I finally got around to connecting the battery to the N64 per the diagram made by Neildo 64. When I turned it on, nothing worked. I took some photos of my work so someone can tell me what is wrong:

Here is the DC-DC Converter I wired:

Here is the Power Connections to the N64 I made. This is on the underside of the N64 Mobo:

Here is a sample of the wire connections I made. I took three or more wires and then added a bead of solder to the tip of all the wires, forming what i believe to be a connection. This is what i did; however, tell me if this is wrong:

just curious but why do you have resistors?

They are used to lower the output voltage of the converter to ~3.3v.

ok I get it now. (I didn't see that you were using a different converter than i was)

Do you know that you only need one wire for the ground and another for the 3.3v. Just saying, it could save a little space.

Where? On the DC-DC or on the N64 power traces?

On the N64. Its what I did for mine.

EDIT: I'll post a pic if you need.

That'd be awsome. I also wondered about my wiring: should i wire 3 or more wires together with a bead of solder or does this cause a short? I showed my "method" in the third photo.

For connecting wires you should twist the ends together, then use solder to hold them in place (not to make the actual connection). As for nothing working, did you check to make sure the DC-DC converter was working correctly before you hooked it up to the N64? A picture of the bottom side of the converter would also help, to see where all those wires are going.

Here is a diagram of how I wired it.(from the underside)

Check your board first, I made this from memory(that means it should be good, but check just in case).

what converter is that... it dosent look like a pth080000

Post by **marshallh** » Mon Apr 10, 2006 4:41 pm

That's a PTH8080. Is it different from a PTH8000? (I don't have the 8000)

test the output voltages with a multimeter, its the only way to know for shur if its the converter or the wiring.

Ya, I got a crappy ass PTH08080 by accident... It only has 5 points, I ended up frying it.

I recommend buying the PTH08000, it's more ideal for this situation.

actually i had originally decided on the 80800 but i didnt get it because samples were backordered. they are almost exactly the same, and if the 80800 isnt broken do NOT go and order an 80000 just because its "better"

anyways. you should check the datasheet then, becuase the wiring could be totally different. and then use a multimeter make sure its outputting the right voltage.
