old DiMarzio slammer HB weird wiring

[ZR]

I have an old DiMarzio slammer humbucker I bought from someone here years ago that's acting weird! I have no problem with whoever I bought it from just trying to figure it out as it seems wired differently to what one would expect.

It says Hamer U.S.A. DiMarzio on the back brass plate, and has triangular screw plates. I thought they were wired as standard DiMarzios which I believe is white and Black together, green/bare is  ground, red hot or +. But, when it's red/green together, then I get a 16.6k ohms reading between b and w. But, I also get the same reading if the red and green are NOT connected. I thought g and w should be the slotted coil, and r and b the slug but I don't get any reading at all between those colors. Isn't that weird? 

I guess I can just hook it up red green together and use the black and white to get 16.6k for + and -. Reverse those if needed for proper phase. But, inquiring minds want to know!

I currently have an all flame maple set neck 1989 Chap Custom with a DiMarzio Tone Zone and 2 old DiMarzio slammer single coils (love those!). I planned on replacing the TZ with the slammer HB. What sound difference do you think I can expect after the switch? 

I like the sound of the TZ but wanted to try the Dim slammer HB with the matching  slammer singles. 

Thanks in advance!!

From Seymour Duncan:

Yep. Black and White together or, more conventionally, Red and Green together.

Thanks so much for taking the time to reply to my post! 

I'm still perplexed that I don't get any signal across each individual coil to me that would seem like something's broken. I have a JB actually tb4j that has one coil with no signal across it so when I put them in series it only picks up the resistance of the one coil that I do get a reading across, something like 7k or something like that. So that one seems to have some type of break in one of the coils. 

So, I guess I'll just install it and be happy that it works in series and compare the sound to my TZ that I like and go from there. 

Still perplexed how I don't get signals across each coil but in series it all works out fine??!

Even though it originally came with Seymour Duncan's I prefer the dimarzio's and think that it's cool to have a 35 year old guitar with old pickups too. I'm just weird that way!

Red is hot, black and white tied together for normal series, ground those two to split, Green and the bare wire to ground.. if you want to reverse phase switch the red and green positions

Thanks for the reply but if you read the details of my post you can see that this is NOT working as a normally wired DiMarzio should. It's somehow very different and operating in some twilight zone/ x files way! 

I've probably installed a 50-100 pickups from many brands and never had problems just following the various wiring diagrams for each brand.  That's why this one perplexes me so!
