I just purchased three stacked humbucker pickups (to fit into a strat body). Anyways, the pickups look exactly the same and were labeled middle, neck, bridge with small stickers. The labels on mine fell off of the neck and bridge pickups. How do I check the output of these so that I can install them correctly in the strat? One should be 6.5k and the other 15k.

Use a a multimeter and set it up to read resistance, then check from the lead wire to the ground wire.
I don't give a shit if you listen to me or not
