I believe I have a Seynour Duncan twin stack on my strat bridge pickup. Its black and it comes with a separate toggle switch to activate either 1 or both the stacked pickups (looks like a single coil though. Best pickup for a strat bridge position with a music man amp to get a nice fat sound I installed it in the 80s and has served me well until recently (actually it got softer and then just no sound after a few days) it just died on me (no sound) . Wiring seems ok but when I touch one of the wires on the inside pickups I get some electronic click. Can someone tell me:-
1. What model it is so that I can try to rewire the whole thing again
2. Could it be the faulty split pickup toggle switch
3. Or is it the end of the pickup - do pickups eventually die out? My two other original Fender pickups (1975) are still good though
If its any help I'll try to post a pic of it

Normally a Pickup will quot;notquot; die in your lifetime. It will weaken slowly but thats about it. If the other pickups in this guitar are fine It would most likely be physical damage or wiring. Artie should be able to give you a better Idea.

Actually . . . I don't think I could say it any better.

This is one of those cases where an ohmmeter, or DMM, would be invaluable.
Just inspect the wiring as close as possible, and look for minute breaks or frays.
