    Hi
    I did just solder the wires for most of the modchips on my wii and it looks ok.
    I went over my wires and i have confirmed connection on all of them, but when i searched for short's i noticed that at least 2 of the wires was shorted.
    Can some pro look at my schematic and see witch of the wires that should be shorted and witch it not should be shorted.

    I have soldered wires to 1-7

    #5 and #7 in your photo are both GND, so you will see continuity between them.

    The others should not be shorted. (You should not have "0" or close to it on your ohmmeter)

    Dosent 0 mean that it's o resistanse = short ? [​IMG]
    Yes it's #5 and #7 witch is shorted...
    Between 6 and 5, and between 6 and 7 thers exatly 700Ohm's resistance, this is ok right ?

    0 resistance = dead short
    infinite resistance = open

    On mine it shows 1 if it's not connected to anything and 0.00 or 0.01 if i short it...
    Should i worry about the 700-1400Ohm resistance between ground and volt ?

    My results vary, can it be my multimeter ? After i taped and isolated the wires i get sometimes 600Ohm's from ground to volt and sometimes 1400-1800Ohm's.
    The thing that i don't like is that i get 1kOhm connection between volt and all the data wires [​IMG] What's wrong ? Is it supposed to be like that ?
    Im afraid to put back my wii together before i have solved these issues or found out that it's ok...

    Yes, that is fine. The only points that are common are #5 and #7. You'll have varying amounts of resistance between the other points.

    Thank you! I just put my wii back together, secured the wires with tape to the side of the wii and it worked perfectly!
    Just have to get an modchip now [​IMG]
    I gues it will be an pic based or an avr on me.
