4 Wire Humbucker and Magnet Questions

Hello All.
I couldn't find a wiring code for these pickups.
I'm waiting on a new meter to arrive to better test wiring polarity but until then, I wanted to run this oddity by the members here.

G&B neck and bridge pickups with the original ceramic magnets north facing the screw side . Neither baseplate marked neck or bridge and with the covers off the neck is zebra , bridge double black bobbins.
The bridge sounded thin , the tone caps were bleeding or another unknown wiring problem caused the multi meter to jump when testing via a short cable through the jack. Height adjustment didn't help and swapping hot/ground wires didn't either .

I had A5 alnico magnets that feel a good bit less in strength with the paperclip test than the factory ceramics that on removal, measure 1.36 long.
Out of the guitar the neck reads 7.99 and the bridge 8.33 with the green & white wires tied together < factory > . 8.2 neck and 8.55 bridge with red and white tied together on the bench. The black wire was ground , red-hot - green and white tied together. In the 3 way switch middle position with the pups in the guitar each measured right at 4.0 like they should or how I think this to be correct.

I am wanting to source shorter A5 alnico magnets and place the north to the slug side and get the two in series. The black and white wires are one coil each pickup and red-green the other coils. Until I can find the start-finish of each could someone tell me why there's more resistance with the red and white wires tied together?

My initial thought is the neck position start wire might be different than the bridge since switching hot/ground on the bridge didn't change anything. The rough cast A5 in the bridge didn't help and seemed to thin it down even more.
Originally it made a slight popping noise through the amp when moving both volumes from 9.5 to 10 . I replaced the 500k audio volumes with 500k linear and popping is gone but it sounds better at 9.5 on the neck pickup. Then I decided to check each pickup wire for a short , changed magnets hoping the A5 would fix the bridge but if anything, it's worse off than before.
SD Alnico Classics seem to be in my future but I want to at least try and get these ironed out and learn something at same time. Always eager to learn but have taken it apart 3 times now.

But did you try reversing the leads on one coil?
