/diy/ - Do It Yourself

Hi, i bought a handmade guitar for a real low price (like 15$), it had no keys, bridge nor strings. I mounted the bridge today and tried to check wether everything is alright and tensed a string near pickups, "played" it, and it made no sound.

I don't have an amplifier, since i enjoyed learning to play acoustic guitar I just bought it to play Rocksmith on PC and borrowed my friends cable to check if the guitar is functional.
The cable is working, thats what im sure of.

Since the pickups are handmade i suspect they are the problem since magnets in them glued off and sometimes move around. Can someone help me and tell me how should they work? Maybe they are polarized wrong? Any help would be appreciated.
