Hi.
I just were "gifted" with a non-working WiiMote (RVL-003) by a friend.
As I could see, the batteries leaked on it.
I rebuilt the positive battery contact, cleaned the board and there was current but it wouldn't turn on.
I discovered a broken trace from pin 9 of the U5 (M3375?) and pin 1 of U2 (6330A?).
Getting ths trace redone made the WiiMote to turn on, but a few seconds later it acts like the battery is dying very quickly.
I took a look at some pictures on the Internet, and all of them seem to have the C11 on board.
Mine hasn't and it seems that the battery leak just turned it to dust and was removed during the cleaning process.
Does someone knows the value of this capacitor? Am I right in think it being missing can cause this problem on the circuit?
Thanks in advance!

Find a repair enthusiast forum and ask there?

I'll be very happy if someone can recomend me one.Dwedit wrote:Find a repair enthusiast forum and ask there?
I understand that here should be a forum more focused on NES development.
But I've got the best answers here.
Up to now I was mostly fixing NES stuff, so...
Anyway, thanks, I'll search for something elsewere...
Re: Missing component on WiiMote
Usually I start of by looking for a schematic, but I haven't been able to find one for the Wii remote.

No luck either
Although I found a clone Wiimote schematics, this part of the circuit is pretty different.
If I understood correctly, this circuit is responsible for the battery charge monitoring and to power up / down the whole the circuit.
Any similar thing that I can use as reference?
Unfortunatelly, my multimeter can't measure capacitance.
If it could, it was just a matter of opening other wiimote and measure it.
Maybe I can build a small oscilator and change its feedback with known capacitances.
This way I could try to find a value near the original...
Re: Missing component on WiiMote
In-circuit capacitance is usually quite difficult to measure, sadly.
Re: Missing component on WiiMote
Any educated guess?
I couldn't even find any of these component's datasheet.
Edit: I already tried a 100nf and a 22nf ceramic capacitors.
No difference noted.
Maybe the problem is elsewhere...

In an 0402 package? "smallish", but that's basically all I've got.

Seems unlikely the cap "fell off the board". If you really suspect the cap, and have a working one you could simply borrow the cap from the good controller to test you missing cap culprit theory.
