    I just got a Fender american deluxe V. This is a active
    only bass. It doesn't switch to passive. I get sound out
    the bass. The volume and tone controls seem to work,
    but when I put it on a volt/ohm meter, nothing registers.
    I put another active bass on and it registers fine. If it
    has an active output, shouldn't it put out a reading??

    What exactly are you connecting the meter to and on what settings?
     
  3. Does it make a sound? if it does dont worry about it, if it isnt registering anything change your batteries

    A few years ago in Bassplayer mag, they had an artical
    on electronics. Long story short, my tech made a cable
    to go from an active bass, into the volt/ohm meter.
    I have two other basses that are active (18 volt). Both
    basses register just under 18 volts with fresh batteries.
    The Fender isn't registering anything. I know its an "active
    only" bass. It sounds ok (great) its just not registering
    anything at any setting. Curious......
     
  5. could be that the output jack is wired differently to what you expect. Many jacks have isolated switches in them that are mechanically actuated by the plug when it's inserted. They are NOT necessarily electrically connected to the signal terminals.

    Older instruments simply had a stereo output jack and used the ring/sleeve shorting trick to connect power to the circuitry.

    So, it would seem to me that the special cable is not suited to the task and that you may find it impossible to check the battery status using this method - although not being savvy with that particular instrument I cannot be sure - just a theory.

    Well answered nifty. Pretty much what I thought was going on.

    Well, how smart are you guys?? You must be correct
    because the bass works fine, I just can't use this
    method of battery checking.
