OT: Not getting reading from neck p'up!

[BrianFantana]

So, being the twiddler I am - I've been messing with pickup changes. When I went to put my SD '59 back in the neck of my Les Paul, I noticed that it sounded like a single coil...I took the joker TOTALLY apart to check the connections and everything seemed to be wired properly, but NO CONTINUITY between certain points.

What in the world could I have done?

Any suggestions / (non-smart arse) advice?

On SD bobbins are:

bobbin 1 Black-White
bobbin 2 Red-Green

Have you tested the bobbins individually? How many ohm do you read ?
The value for each bobbin should be similar. If the ohmmeter display 1, the bobbin is cut.

If both bobbin are ok, connect the white with the red, and mesure between Black and Green.

If all mesurement are ok, try to connect the jack directly on the black (hot) and green (ground).
