I'm not very familiar with the 4th gen but from what I've seen it seems the battery is a 3 pin? Black is ground red is positive and a third white or yellow wire is presumably some type of thermistor. I would try applying gnd to black and 3.7v to red on the motherboard, check if it powers on, if it doesn't then it expects a signal on the thermistor pin of the battery. On most phones you can get away with pulling the thermistor pin on the motherboard to GND essentially 'emulating' a thermistor, I suspect it would work similarly on the iPod
