Heres an easy way of testing to see it both coils are working and all the poles too, plug your guitar in to your amp (hope its not an M-80, with chorus) turn it up a bit, get a small pointed metal object like a small screwdriver, select the bridge pickup with your selector switch, and touch one of the poles on one of the coils on the bridge pickup, you should hear an audiable ‘click’ and the screwdriver should stick to the pole, when you do this to the neck pickup you wont hear the click, cos obviously it’s switched off, go back to the bridge pickup and test all the poles making sure you can hear an even volumed click on each one, if they all sound ok then you have done no damage.

can you go into a bit more detail?? do you mean the pole peices?? or do you mean a whole coil popped up out of its housing?? i cant picture whats going on here.
