Kinman Fatmaster High Pitched Noise

[night_tide]

Hey ya'll, this is my first post on here. I recently installed a pair of kinman fatmasters in my cp jazzmaster and noticed a high pitch ringing hum on all pickup selections. There isn't any buzz or much other hum and everything appears to be grounded. Not sure what the issue is or if it's my lack of soldering technique. Any suggestion helps thanks!

Yeah, something is wrong there. If I was guessing I would say that it was improperly grounded somewhere. Maybe crack the guitar open and use a multimeter to make sure you have continuity to ground from everywhere.

Maybe microphonics. If you gently tap on the pickups, do you get the ringing sound?

I figured, cause when I adjusted the pickup mounting screws the sound went away

These (apparently) have 3 wires - how have you connected them up?

Pictures of the wiring harness may help.
