I've been having pickup issues with my Tokai
The bridge pickup would sometimes short out, So Took all the covers off, checked for breaks, shorts etc and found that the black hot wire was going straight to earth, so I disconnect the pickup complete and it still goes straight to earth.
So I take it out and check baseplate to hot, short. Baseplate to green and get 14k.
Seems that the baseplate screw must have been hitting the braiding on my neck pickup and as the wires appear to be the wrong way round was shorting out the pickup.
