Solved Why is the Wii not turning on?

[Stitches]

Alright, well the 3.3v short is gone. That's one problem down. Next, can you explain what you mean by "not getting power to the board"? Have you measured the output voltages of the PMS without the Wii connected? I'd give your PMS a clean and do that.

So I cleaned up the PMS and I measured the points on the board and some parts would get power but the 3.3v, 1v, 1.15v, and the 1.8v were all not getting power

How are you testing for power? Do you have 1 or 2 batteries hooked up?

 

[Joey Macaroni]

1 battery

1 battery

Try testing with 2. I had an issue where my PMS would turn everything off the moment I turned it on due to not enough amps. Everything would drop to 0 once I turned it on.

Also just so you don't make that mistake like others unfortunatly have, if you're wiring 2 batteries, you have to wire them in parallel. Connecting them in series WILL kill your PMS

I'd also check the voltages of your batteries. They may be below the PMS safety shutoff threshold

 

[Joey Macaroni]

I tried both batteries and I got nothing. They are both 3.18v.

You might want to read up a little bit on lithium batteries before proceeding, particularly voltages:

3.18v means the cells are effectively empty and below the PMS max safe discharge threshold. The cells need a full charge before the PMS will turn on

 

[Joey Macaroni]

Sorry for the late response I have been busy lately. I charged the batteries and now I am getting 3.6v going to the pms but I am not getting anything on the 3.3v 1v 1.15v or the 1.8v.

And you've definitely wired the power button correctly?

 

[Joey Macaroni]

I think so. I wired one wire to the pad that says BTN and the other wire to ground they are both wired to a button. I measured it with my multimeter and it said there was a good connection.

 

[Stitches]

Just making sure, BTN doesn't have continuity with ground when the button isn't pressed right?

 

[Joey Macaroni]

It does not

 

[Stitches]

Hmmmmmmmmmmmmmm. Can you post photos of the current wiring?

 

[Joey Macaroni]

Yeah

 

[Stitches]

The only thing I see potentially out of place is that SCW and SDW look like they might be shorted. Aside from that, I see nothing visually wrong.

 

[Joey Macaroni]

I checked and the SCW and SCW are not shorted. Do you think that the PMS might be dead?

 

[Stitches]

It could be. There are a couple more things we can check before calling it. The first that comes to mind is to try holding the power button down and see if the console boots. It's possible that the PMS was accidentally set to power switch mode instead of button mode.
