When i opened up the cavity of my washburn dime guitar, i noticed that the wiring was a little strange. The black and greens are both soldered together and taped off on both pickups and the red is used as the hot and white and bare are both grounded to the back of the pots. Why would someone do this? What is the purpose? Normally the red and white are soldered together and taped off. The black is hot and the green and bare are ground.
