Need Fender Squier Bullet 1 w/3 pickups, 1 vol, 1 tone wire diag

Standard J-Bass wiring is parallel. Not series.

To run the pickups in series, the ground of one pickup would feed into the hot of the next. That's not what comes from the factory.

That's a Vintage Modified series from 2007. i seen info stating they were made of either Indian cedar or agathis. if that's indeed what it is, the pickups will be import Duncan Design type. Your best bet would be to contact Fender directly. Their contact links ar where-

> There are plenty of ways to wire this guitar...check out wiring diagram 2 humbuckers 2 volume 1 tone 3 way switch Google Search

That guitar features two single coil pickups when stock. If, however, you or someone else installed a 4 conductor humbucker in the neck and you want to access other tonal options, check out the Seymour Duncan web site- they have tons of easy to understand diagrams- you just need the soldering skills to make use of them!
Make your selections on this page and good luck!

check at seymourduncan.com...your humbucker needs to have 4 conductors in order to tap coils...which is what I presume you want to do with the push/pull...

Need more info: 1- does the volume control still change the level? 2-Does tone control still change the tone? 3- What happens when in the center position on pickup select switch? Put pickup switch in center position (both pickups active). Then take a coin and tap on the pickups. Does bridge pickup sound lower? Lastly remove rear electronics cover and inspect all wiring for something loose or disconnected.

my guess is two positions at one end work(aka 1 and 2, or 4 and 5)? if yes, then 2 of the pickups are wired wrong. (if 1 and 2 work, which are the forward positions, then the middle and bridge pickup are wired wrong, etc.) the problem is there is a variety of 5way switches that are different. i would guess yours is "import" style. are there 8 lugs in a single row on the back of the switch? if yes, you probably have an import switch. best i can do in text is tell you that the middle two lugs are common. this means one goes to the volume pot, and there is probably a little jumper between the two lugs as well. now there are 3 lugs on either side of those 2 common lugs. one set of 3 will probably run to the tone pot in some fashion or be empty. the other set of 3 lugs is for the pickup lead wires. it sounds like at least one or two of those lugs are empty but shouldnt be, or are wired wrong. i cant tell you colors of your wires without seeing it, but this is how it should be, with the exception that the tone knob will probably be on the bottom 3 lugs somewhere. 1 would be the neck pickup, 2 the middle, and 3 the bridge hope this helps, feel free to post a pic of your wiring, etc

TRY REPLACING VOLUME CONTROL BUTTON.

It's wired like this: http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=HSH_1v_1t_5w

se3veral things have to be ruled out, start with the cord that your using to your amp, is it good? next is the volume on both the guitar and amp also good, the last thing that should be wrong is the pickup itself unless a wire is broken off of it, you can usally check this from somewhere on the back of the guitar, if all the wires are good, check the two volume controls and on the back of the amp check the wires going to the speaker.
