Half of Pickup Lower Volume

    I've been working on wiring this bass for a couple days (I'm a slow learner), and finally got it all working this evening.

    It's a P/J with Fender Japan pickups, wired 3-way switch, Master volume, Master Tone. It took me a bit to get it all worked out, since there wasn't a very good diagram online, but it finally 'worked' tonight.

    The problem now is that the EA side of the P pickup sounds good, but the DG side makes virtually no sound. Tapping with a screwdriver, the EA side is loud, the Jazz pickup is loud, but the DG side probably gives about 1/10th volume of the rest.

    I checked, and all the wires are still attached. Does it sound like my pickup is DOA?
     
  2. looks like it, you could also try to wire the P pickup straight to the output jack, and tap again, if still the same then the pickup has a problem, if loud and clear this way, then there is a weird phase cancellation happening

    You can use a meter to take DCR readings of each coil for you P pickup by putting the probes on the solder blobs (you might have toscartch a little to make a connection; and be careful not to damage the coi wire). They should read about the same. If the D/G coil is a lot lower it might need a rewind or the solder joints redone.

    It seems like the magnet itself just isn't as strong. I can't even get it to pick up a pickguard screw from more than half an inch away, and the other side grabs it much farther than that...

    I had a similar problem and traced mine back to corrosion in the wiring of the E-A coil... Somehow, a beverage had been spilled in there... Too bad really, because up to that point, it was far and away the best passive P pup I had ever heard, (stock pup in my '96 MIA P)...

    A lower magnetic pull... That's a new one to me, but totally plausible... Luckily, replacements are fairly cheap and plentiful!
