Cold solder joints This can happen if the joint is moved or if you blow on it. Often the eyelet isn t heated enough to melt the insulation on the magnet wire. Just re-apply heat to the solder joint if you see no signs of coil damage. On humbuckers the small hookup wire connected to the coil can have a bad or cold solder joint. The humbucker coils are more delicate to work on and extreme care has to be taken when removing the insulating tape to repair or check out if the coil is damaged.
