    Hey guys! first time posting and first time Tele build.

    I have a 902D pre-wired control plate (3-way), Fender vintage-style pickups. Only the bridge pickup works, volume pot does not work.

    I have searched and it must be a grounding issue but I have re-soldered the grounds for the two pickups 4 times already and it hasn't fixed it... can you guys help?

    Is the third tab of the volume pot (toward the bottom of that photo) grounded? I can’t tell from the photo because of the black ground wires crossing over there... It needs to be grounded, often done by folding it back and soldering it to the pot body.

    Ground that & I think it will all work fine.
    And give the supplier a hard time! That’s a rookie mistake imho...

    Thank you! that ground was the problem for the volume pot.

    The neck pickup still doesn't work....

    Neck pickup should be pretty straight forward, white to first tab on right and ground preferably to volume pot; and that's how yours looks.

    I'm assuming it isn't working in the middle position either? You tapped the pickup with a piece of metal? (Gently, don't scratch it!)

    I would probably exercise overkill and clean up the solder, especially on the pot for the pickup ground and while I have the pickup leads loose check the pickup with a multi-meter, make sure it reads 7.whatever and isn't a dead pickup.

    I feel your frustration, happened to me recently and it was a dead pickup.

    This is surprising to me. I have installed a couple of these 920D loaded and pre-wired sets and the work looked very nice, but this one was clear - should have run the leg of the cap all the way over to the pot.
    Mattdon7, you called it "902D." Was that just a typo for 920D or was 902D actually the name the vendor used? Just wondering in case some fly-by-night outfit was trying to capitalize on name recognition for 920D.
    I hope your neck pickup ends up being OK, keep us posted.

    Yeah it is 920D, my typo.

    I just took it apart and checked the pickup, got it on my volt meter at 20k Ohms and it reads "1." which means too much resistance (infinity).

    I checked by bridge pickup and am getting a reading...

    Does this mean the neck pickup is defective?

    It should measure somewhere between 6K and 8k.

    I called Fender and it is out of warranty (over a year old).

    Was the neck pickup provided by 920D as part of the pre-wired package? If so, and it arrived inoperative, I think you should expect them to replace it. Fender's warranty should be N/A to you in this case. If, however, you had the pickups yourself and just bought the plate from 920D, I guess this is too bad. That said, there are a lot of guys here who wind pickups and it ought not to cost more than a pittance to get the existing neck pickup re-wound, or you might even be able to fix it yourself if the break in the wire is at the little ferrules where the ends of the 42 gauge wire is soldered off to.

    Thanks guys, I will see what I can do. Bought the pickups separate from 920D.

    Here is a picture of the back of the pickup in case any flaw is obvious.

    Interesting...usually neck pickups are wound counterclockwise/north pole up and if some hum cancel is desired, the bridge pickup would be wound clockwise/south.

    Vintage 50s Fender pickups are typically both counterclockwise/north because there was no need for hum cancelling because there was no switch selection for both pickups until the mid-late 60s. Then Fender decided to reverse wind reverse polarity the bridge pickup to clockwise/south.

    If you own a real vintage 50s bridge pickup wound counterclockwise/north then you may want to use a RW/RP neck pickup like yours for some hum cancel.

    I am curious which way your bridge pickup is wound in relation to your clockwise/assumed south neck pickup.

    On your neck pickup the coil wire finish wrap is on the left side (from above, leads facing down) (right side the way your picture is oriented) and I do not see it wrapped around the eyelet where the lead is soldered like I do on the ground side. You might have a bad connection on the hot side. If the pickups are under warranty send it back. If not, there are many on line places that can fix a broken end wrap, pretty cheap actually, if that's what the problem is.

    Put an ohmmeter on the leads, that'll tell you if the pick up is good or no

    The Amazon link took me to the American Vintage 52 "Original"... Is that right?

    Your pickup definitely looks backwards from what is published. Huh.

    Using a modern 3 way configuration one pickup should be RW/RP from the other, even though Fender doesn't even do that on all their own guitars.


    Now I'm really curious about the bridge pickup.
