    Hey all, hope I can get some help on here since I'm still a bit green to wiring.

    So I wired my BKP Blackhawks into my Ibanez S1520FB using this diagram (https://www.bareknucklepickups.co.u...ez_Style_5_way_Switch_1Vol_1Tone__48abdab.pdf) from the BKP website. When I finished, positions 1 and 5 (full humbucker mode) worked as they should. However, position 2 sounded exactly like position 1, and positions 3 and 4 were only one of the coils from the bridge, which gave me a disgusting shrill tone, like a wah tilted all the way forward. I assumed this is a polarity issue because of the Ibanez switch.

    Obviously, the diagram says that the magnets for the neck must be reversed. Some people on forums (https://forum.bareknucklepickups.co.uk/index.php?topic=27345.15) said to switch the black and red wires of the neck, then flip the neck pickup around. I switched the wires but haven't yet flipped the magnet or pickup. Positions 1, 3, 4, and 5 work completely fine. However, position 2 is dead.

    My questions are:

    How can I fix this?
    Does the Blackhawk need to be reversed due to its different construction/magnet configuration than the rest of the BKP lineup?
    Would I need to swap the magnets around or would rotating the pickup suffice in changing the polarity?

    Obviously, my understanding of wiring and electromagnetism is surface-level at best, so I appreciate your patience with what's probably a really dumb question. Thanks in advance and have a great weekend everybody!

    rotating the pickup doesn't do anything about polarity. the magnet needs to be reversed in relation to the coils.

    that being said...why not just get a regular 5 way switch.

    I've actually never had a problem with the 2502 and magnets. Can you confirm that the switch in your s is a 2502?

    Thank you for the quick reply, and yes it is a 2502. If I truly can't make this work, I'll probably end up replacing the switch but I'd rather see if I can while I have the current config.
