I have an adapter that got loose so now I should determine the polarity of wii female 12v dc port and the adapter's 12v output cables... I'm on vacation so I don't have any multimeters... Of the cable, possibly unshielded cable is the ground... but can't estimate for the port in the wii which looks like this... ..___ /......| |..O..| |......| |..O..| ------- So could someone help me? Also what happens if I give the 12v dc in wrong polarity to the wii? A burned fuse? More serious damage, nothing?
