Slug coil = south polarity on a TB-16 Custom/Hybrid 59 bridge?

I'm in the middle of trying some new magnets for my C/59H bridge pickup and upon removing the stock magnet the compass is showing me that the magnet was oriented with the north to the screw coil and south to the slug coil, which seems to go against normal convention. Is this right or am I missing something? I guess I'll find out when I get it all wired back together but I'd hate to take it all apart again. Any help is appreciated, thanks.
 
Stock is north to the slug.

Do you need help with the sitch?

Thanks, I'm rewiring my Strat (2HB, 2 Vol, 1 Tone + Coil Split) and am getting confused with the situation.

Does it make a difference what way the magnet is? I'm 99% sure the magnet was north to the screw coil (should have taken a pic!) so I just put the replacement in the same way. The way it was wired was fine, no out of phase weirdness, which is why I followed suit. This was a brand new custom shop pickup so i assume they got it right but who knows.

Also, does the trembucker TB-16 split to the 59 or Custom coil? I know it's usually to the slug (Custom) but I read Mincer say the trembucker was different. I'm trying to wire a partial split with a resistor to ground on the push-pull pot but I may just do this for the neck only.
 
Mag flip (and wire flip) is used for the scheme for hum cancellation when splitting to inner or outer coils. If you have the guitar wired up just tap on the coils with a screw driver to see which one is active after you split. Yes, the Custom coil is supposed to be the slug.

Just finished up and confirmed that it's tapping to the slug coils on both pickups. Somehow, I didn't screw it up the fist time and everything seems to work as it should. For whatever reason, the north going to the screw coil seems to work and was how it was orientated as stock. Maybe the trembucker is different for whatever reason? I might try to email SD and see if they can confirm it but for now it's all good and works as is. The rough cast UOA5 works as intended, took a lot of the brightness away I was getting with the stock A5.
 
That's good. Are you getting hum cancellation from the inner slug coils split?

So this is a new pickup? Interesting that the mag came flipped.

As far as I know, mags don't come stock flipped. There wouldn't be anything different about a pup just because it's a tb except the longer bobbins.

I have the regulars 60Hz hum when split, I'll have to check to see if hum is cancelled in the middle position. These were bought new from SD around 2017, a Jazz for the neck and the 59/CH trembucker for the bridge. They were from the custom shop because I ordered parchment bobbins.

Yeah I don't why it was like that but it seems to work as far as I can tell. I figured rather than try what I think it should be doing, I just left it it how it was. Is it correct that the middle pos will be out of phase if the magnet is flipped?
 
If only the mag is flipped, middle position is out of phase. Mag flip and wire flip gets you back to in phase but then inner or outer coils split are rwrp.
 
I believe there has been (just a few) instances reported on this forum where something left the factory with the magnet flipped or something else out of sorts. It is extremely rare, but things happen even to the best companies.
