How can I tell if a pick up is broken?

Discussion in 'Pickups & Electronics [BG]' started by MadPink, Apr 29, 2002.


  1. When I place the switch in the up position on my Rickenbacker 4001 i get no sound what so ever..but when I have it in the middle or lowest position it seems to work fine. what is wrong here? is it the switch? loose wire? pickup? what can I do to be able to tell? and how can which pickup is broken?
     
  2. come on...i need some help here.
     
  3. Be patient, MadPink. Sometimes it takes these guys a while to answer.

    If you want to test the pup, get a couple of wires and do a direct short from the pup to the jack, and then play. If there is no sound, then it's the pup. Otherwise it may be the wiring or maybe even the switch.

    Rock on

    4001 eh? Here's a silly question...are you plugged into the
    Stereo or "Ric-o-sound" output? :)

    That aside, here's a schematic that (I think) covers your 4001...

    I think Eric's got the right idea...start off going straight from
    the pickup's hot wire to the output. Then work your way
    closer and closer to the output -- one side of the switch then
    the other, etc.

    Referring to the schematic, the worse case is that it's possible
    C1 or C2 AND it's associated Bass tone or Treble tone pot
    are bad, i.e., shorting the pickup's output straight to ground.
    To verify this, you'd have to un-solder one of the leads of
    C1 or C2. It could also be the output jack.

    Before it comes to that though, try Monkey Man's idea - no
    soldering/de-soldering required :) . You can get a package of
    four of these itty-bitty 'jumper leads' at Radio Schrack for
    less than $10USD to do all the connection checkin'...
