Ok, problem. The xmods I bought isnt working. I got it 'as is' from radio shack. they didnt know what was wrong with it. It all works fine, except the battery pack. For some reason, when I measure the voltage at the battery pack, it is nil. Yet when I use my own battery pack, it works fine. So where the heck can I get one, and is there any sort of known problem with them being messed? I havent had time to look at it too carefully, so any help is appreciated.
