Wiring Diagram

Post by Shanebeck »

Can someone please post a wiring diagram for the snesp please? I can't seem to get mine to work and I'm just so frustrated! I keep reading on the forums but nothing seems to work! Someone please post something even a diagram made up on microsoft paint would be perfect.

Link, this should help. If this doesn't please try to specify more, is it getting it connected with your batteries, are you not getting an image on screen?

Sorry maybe I need to be more specific. I tried to hook up the snes to batteries but it didnt work when i turned it on. I plugged it into wall power and the snes worked so it isnt broken. If someone could post a diagram of the snes hooked up to AA batteries it would be very helpful.

OK, so to try and help you a bit more, a few questions?

1. What kind of SNES are you using? (Original, original v2, mini, fc twin, retro duo)
2. Have you modified the SNES in any way yet? (Like removing the power button)
3. What kind of screen are you using?
4. How many batteries are you running and how?

I ask these questions because

1. All the official consoles should be the same but I know the retro duo does not use a regulator.
2. If you have removed the power button you have to solder specific points to keep the system always on.
3. Assuming it's something similar to the PS1 screen, in most cases its usually easier to feed the power to a switch then to the screen and then use 5v line from the screens regulator to power your SNES on.
4. You may not have the proper voltage necessary to run the SNES.

I'm not sure if there's a wiring diagram for the SNES aside from one in Ben's book so you're just going to have to research. I've never worked with an official SNES but my understanding is this. You need 5v to get it running. Normally the power adapter has 9v of unregulated power going to a 7805 regulator. The regulator then drops this down to 5v.

Now I don't know how many batteries you have or how you're running them. I'm going to guess and say you have 4 AA batteries running in a series. That's 6v. To my understanding you need at least 7v running to the regulator before it drops out and stops working. And I'm pretty sure if you feed the 5v line 6v that you'll fry your system. Anybody, please feel free to correct me if I'm wrong. I know that in a thread of his LOB mentions using a regulator from TI to get a SNESp working with 4 AAs.

So, if you definitely want to use AAs I would recommend PM'ing LOB to see what kind of regulator he is using. Either that or use 5 AAs to get 7.5v. Aside from that the only thing I can think of is make sure that you have ground connected from the batteries to the console (easy thing that some people tend to forget). Good luck.

I am using 6 AA batteries, a snes mini (I believe that is the v2), and my screen is a hip gear that takes 12v. Please help!

Check the battery compartment terminals with a multimeter. I had this be an issue with me on a Genesis radica where some of the pieces in the compartment weren't making contact with the batteries and where I should have been getting 6v I was getting only 3v.

How do you currently have your batteries connected to the SNES? Where on the system is the positive terminal connected and where is the negative terminal connected? Check your connections with your multimeter to see if you have the proper voltage going to where it needs to be, it could be a cold solder joint.
