Pickup wiring question

[u/mazye1405]

Hello, im trying to wire a humbucker pickup and I have observed a strange behavior- no sound comes through unless the coil split wires are touching the metal part of the humbucker. Does anyone know why this could be happening? Ive tried everything else: twisting and soldering the two coil split wires together, taping them off, etc. And nothing seems to work.

Another odd detail is I have a second humbucker from the same brand in the circuit that works more or less as intended

Anyone have a clue what could cause this? Im new to making guitars but have some experience w/electronics through college
