Thanks for the replies folks. This is my daughters unit, who having taken after her old man - is VERY particular and careful about her equipment. The Wii is a couple of years old and I'm sure is out of warranty.
I can guarantee that the remotes have never been dropped. They are also spotlessly clean, and have no corrosion what so ever. She also has and uses the rechargeable batteries, so the first thing I tried was installing a fresh pair of alkaline batteries to see what happened. I was thinking the NiMh batteries may have exceeded their usable number of cycles. But it is a definite draw pulling any batteries down.
JD: I'll try comparing the resistance between the battery terminals on both remotes and get mA readings from both as well. (I loves
me some Fluke 77, LOL.) I was hoping I could find a schematic so I could take a "split half" approach to narrowing down the draw rather than going about it haphazardly since I don't have a clue of what the power source path is.
I've already ordered her a new controller, but I do love a good challenge - so......
Ok, here are the results....
Now..... where to look first?
I really don't want to tear apart the good one - you know?
