Why do pickups stop working?
There are several things that can cause your pickups to stop working. The biggest problem is ICPC and getting strings snagged in the coils with exposed coils or covers removed. Check your instrument to make sure you don’t have active pickups. If you do, maybe the battery needs to be replaced. When pickups are taken out of the instrument, they can be damaged just by taking them out of the box. I’ve seen pickups that have been gouged with screw drivers, solder drips on the coils, magnet wire broken when tape was removed from coils, magnet wire and coils broken by height adjust springs, covers that are too tight and break the outer coil and just rough handling. Be careful with your pickups and put them in a safe place if you’re not going to use them. Keep them carefully wrapped up in tissue and put in a safe place. Don’t place them next to each other where the magnetism can be affected by close proximity. It can change the magnetic orientation.
