What is the best way to connect magnet wire to the lead wires?
At times you will have difficulty soldering certain insulation s on magnet wire. The lead wire and must be physically striped by using a 600 grit sandpaper or using a chemical stripper to remove the insulation. Note: You have to be careful in removing the insulation as you can fatigue the magnet wire. I carefully tape each joint to reduce the bare copper wire from oxidizing and failing at a later date. I see many contacts oxidized at the eyelet s on Fender style pickups. A good insulating coating on the solder joints such as wax potting helps keep moisture from oxidizing the bare copper wire. If magnet wire had no insulation the wound coil would completely short out. Older insulation s can break down over time making the pickup fail. If your pickups are subject to lots of moisture especially guitar cases left in hot car trunks or in the sun, absorbed moisture inside the case can make the pickup rust and coil to oxidize. Making sure your solder joints and connections are protected from
