Re: Universe first year greendot
This is strange. I would say neck and bridge have been exchanged. The upside down marking on the neck side and single should be correct, but I have only seen it with B in bridge and N in neck. But I have also always seen the wires shortened from factory and that cable from your B1 is very long.
I have also only seen red as hot, green+bare to ground and black+white in the middle for splitting. So in your case the outer coils are used and with the same magnetic pole as the single coil you will never get hum-cancelling in positions 2+4 and that is what you hear.
I would change the wiring or maybe someone else has an idea?
If you want to change the wiring exchange
white with red
black with green
and then white+black go where red+green is now.
And then finally black and white from the single coil need to be exchanged with each other to be in phase.
Hope this helps.
