Do you know someone with a digital multimeter that has a testing mode? Or just buy one; those are dirt-cheap nowadays and it's always good to have one to check loose connections. Just connect the needles with the soldering joints of the pickup and the preamp board. If there's a current, it's the pickup (or preamp). If not, it's the wire.
If you want to find out if its the preamp or the pickup, then you can remove the battery temporarily to disable the preamp and short the pickup and the output jack. If you see a significant current on the output jack (you can short the working pickup for a comparison how much current you should get) when picking a string, it's the preamp.
