Hey Unk!! How dare you apologize to me??? Sorry about apologizing. rofl Steve K has good info on his site for the most part, I've used that chart as a reference before. Since I haven't actually wired a guitar with diMarzios, it's still second hand info for me, hence the "not 100%". Don't rush getting back with the confirmation on the coils. That can wait. Time with the baby and wife can't.

Hi there! I'm back with info Here is what I could gather by tapping the coils with a screwdriver: Position 1, 3 and 5 are just perfect. Everything works as intended with both coils active. Now, position 2 and 4 are a different story and it's a bit of a mess. To begin with, it's more difficult to say which coil is active and which isn't on a pickup, as both seem to "sound" but sometimes one much quieter than the other. Is this normal? Now to the facts: Position 2 (should be neck inner coil and middle coil nearest to the neck pickup): Bridge pickup = 0, this is good. It's not active and it doesn't make any noise. Middle pickup = both coils seem to be active and at the same volume (output, whatever). Neck pickup = outer coil low output, inner coil high output (this seems "ok") Position 4 (should be bridge inner coil and middle coil nearest to the bridge pickup): Neck pickup = 0, as intended, perfect!! Middle pickup = seems to be backwards. The coil that seems to be active is the one away from the bridge. Bridge pickup = outer coil high output, inner coil low output (also seems to be backwards) If you need any more information, or want me to perform some kind of experiment, just tell!

I think this is good start. One of the reasons you get similar soundings by tapping the pole-pieces of adjacent coils, it the lines of flux are distrubuted across both coils. You can do a better job by laying a screwdriver, or whatever flat across the coil, pointed inward and touching it's pole-piece. that way, when you lift the tip, or drag it away from the pole-piece, the change in the magnetic field affected by the screwdriver, is right over just one coil.
the fact that they aren't all that different for the middle wouldn't surprise me, but there seems to be a difference, depending if you are in position 2 or 4. That suggests more errors.
I look at the original diagram again, and see i can reconsile it with your description.
if you can connect a meter to the end of a guitar cable, and test the polarity of the pulse that occurs when you pull the screwdriver off of each coil, that would help too.

Sorry, I didn't quite understand what you mean... can you explain it again?
Sure! I have a multimeter so I will do that asap.

Ok Unk, I did it the way you told me and the results were exactly the same, so what should I do?

That should solve the bridge pickup issue in position 4, but what about the middle pickup? It also seems to be backwards. Also, what about position 2? Again the middle pickup is giving troubles as both coils seem to be active

As far as position 4 is concerned, it looks right on paper. According to north and south go, it should hum-cancel correctly with the middle pickup wired as shown. I wonder if the middle pickup has the north and south in the wrong places? Position 2 both coils active? That just doesn't make sense. There is only 1 coil connected, according to the drawing. I can't find any way for that to happen. I'm stumped.

Hmmm don't think that it's an internal short, as in position 4 ony one is active.
