newb to the forum. I left the battery in my GPS 12xl in the console of my jeep and long story short I ended up having to clean up a good amount of corrosion. Laser cutting a few new pieces for the "black" side of the 2 battery bays to rebuild the housing and holder of the (black) terminal. Along the way I had to stow it away for a short time (1 year) and revisiting I found that the black wire is totally missing now. Where in the heck did it solder onto the board? I should have taking a picture. :eek: I'm totally expecting someone to say to say - toss it. But it has sentimental value. What kind of girl would buy her boyfriend an awesome GPS like this... my wife now of 12 years :-).
