    I recently replaced (or had a friend replace, rather) my passive jazz pickups for active ones. While the pickups sound great, the battery won't last longer than a week or two. Does anyone know of any common wiring mistakes that could cause this?
     
  2. Don't leave the jackplug in the socket.

    You've installed active pickups or an active preamp?

    +1 on making sure you take your instrument cable out of your bass whenever you're not playing it. That's likely it.

    Yup, even if I go just to take a leak, I unplug the cable so the battery doesn't leak. :D

    Thanks for the input, but its not the cable being plugged in. The battery goes dead in the case without me playing the bass at all. Its my backup bass so, it hardly ever gets played...and I'm finding its not much good having a backup if every time you pull it out its dead!

    Also, to answer "guy n. cognito's" question, it was active pickups that were installed, not a preamp.

    Any other thoughts out there?

    Check our wiring. Input jack should be switching the battery ground on when you plug in, and off when you unplug. Either wired incorrectly, or some other area of the wiring harness is grounding the battery.

    Unplugging is only useful if there is a switch built in the jack.
    Is there a TRS jack on your bass ?

    stop buying cheap batteries

    definatly sounds like the Pickups are staying powered for some reason

    +1 on TRS Jack.
     
  10. This issue is quite simple: You'll need to upgrade your output jack on your formerly passive bass.. The current jack is allowing your battery to drain. You'll have to get the same type of jack that are found in active instruments.
     
  11. right...
    stereo jack...

    signal to tip (as before)
    ring gets the ground
    sleeve (middle bit) gets the battery negative...

    when the lead is plugged into the jack, the battery negative connects to the ground, thus "powering up" your preamp...unplugged, the circuit is open and there is no current draw on the battery.
     
  12. What pilbarabass said is correct.

    One more piece of advice - don't let this same friend work on the electronics of your bass anymore.

    Sounds good. My friend (who will not work on my bass again, thank you slyjoe) did not replace the original jack. I'll give it a shot. Thanks for the feedback!
     
  14. If that's the original jack, that's the problem. It probably has two lugs on it. You need 3.
     
  15. +1...

    he's probably wired the battery negative straight to the ground = ALWAYS on...
