Having difficulty with my Bridge pickup

[slimedog]

Installed a set of SD P Rails with Triple Shots in my LP. I'm attaching the diagram that SD sent me.

So the neck pickup works great. The bridge pickup works but is very quiet and I get A LOT of feedback over the sound. I have a 3 way switch installed where the neck pickup alone works as it should and in the middle position both pickups work. If I tap on them with a pick or screwdriver I can hear it through my amp. The problem is if the switch is to the bridge pickup only, again I get A LOT of feedback from the amp and minimal sound from the strings. The pickup height is set not far from the strings. If I tap on the bridge pickup when the switch is to that pickup alone, I get no sound through the amp.

I've checked all of the wiring on all of the pots, switch and jack and everything is secure with nothing touching any walls in the guitar. I'm stumped.

Any help or thoughts are greatly appreciated.​

Usually when someone is having these kind of problems and they say they have checked all of the wiring/connections...they haven't. Because the problems are usually with the wiring/connections.

First thing to check/double check is the soldering on the Triple Shot, that's the easiest place to screw up. It's also the most fragile, so be very careful.
Next, make sure you have the hot wire going to the tip of the output jack and the ground wire going to them sleeve of the jack.
Then check all of the other connections. When I say "check", you are looking for...
the correct wires soldered to the appropriate lugs,
no stray wires,
no "cold solder joints",
no blobs of solder.

It may be prudent to unsolder all the connections and redo them correctly.

Thank you for your response. The triple shots were presoldered when they arrived but I will recheck everything again and see if there are any weaknesses or disconnects.

I have that same setup in a guitar, and I've experienced the same issue. I recommend checking the little slider switches on the bridge triple-shot and make sure that they're both solidly to one side or the other...

the triple shot wiring is pretty straight forward.

do the switches on the triple shot make any difference? how about the phase and series/parallel switches?
