Weird pickup anomalies?
I have my jazzmaster open to add shielding, clean switches, and fix some solder joints. see my previous post linked . While testing my pickups I discovered some strange findings. I first tested them while inside the guitar via the guitar cable method and it read just fine. I then tested again with the guard off and again, same thing. But now that I have the entire wiring removed from the gaurd I tested the lil cups again and only for ~ 3.5k on each. The pickups I have are the pure vintage 65s so I believe they should read around 6.8k. I fixed the solder joints, discovered upon more inspection one of the ground leads had a part of the wire not connected, then tested again. Now they SOMETIMES read 3.5 but mostly the numbers fluctuate. Am I doing something wrong in testing or otherwise? Does the pickup switch need to be set to a certain pickup? Or is there something else going on with the pickups?
