Batteries Consistently Dying.

    I have a Tobias Growler 5 with active setup. I have replaced the input jack, as the original went bad, and replaced the 9-Volt battery connector becasue it was trashed. Now, my batteries die so fast that I usually only get one session out of the bass before having to replace them.

    Do any of you wiring gurus have any suggestions that I can try before taking it to a shop and having them look at it? I am willing to do this, but if there are a couple of suggestions that I can try, I would be grateful.

    Take a look at your soldering work, maybe you connected some wires the wrong way.
    It could be that your battery is wired so it gets "shortcut". This will suck your battery dry in a few hours.

    It might be your jack. Sometimes, the metal inside that activates the active electronics fails to disengage and the battery keeps running...

    Here is a picture of the wiring:

    <img src="http://www.frolicweb.com/images/best.jpg">

    The red wire is attached to the shortest stem of the input jack and that wire goes into the circuit board which is labeled "Guitar Jack"

    The Green wire is attached to the longest stem of the input jack and goes into the circuit board which is labeled "Gnd"

    The Black wire is attached to the "medium sized" stem of the input jack and goes into the circuit board labled Guitar Jack. There are two posts in the circuit board for the "Guitar Jack".

    Does this show anybody anything? Help...please...

    If the soldering job on the input jack isn't done carefully the excess solder can cuase a short circuit. Make sure none of the solder (or bare wire for that matter) is touching any of the other wires or posts on the jack.

    Like's been said, it could be your jack. It's probably a stereo jack
    with the second "hot" lead used as one side of a switch terminal
    to ground. That is, when you plug in, the ground sleeve portion
    of your plug connects the 2nd hot lead and ground turning the
    preamp on.

    Here's a pic from Stew-Mac :) that may help...


    I had a similar problem with an Ibanez I got a loooong time ago.
    It was 50% off (demo model). Brand new batteries didn't last more
    than &frac12; hour. I figure because it was a demo, folks were constantly
    pluggin' in and may have messed up the jack / "switch".
