How can i check that the pickup is working? I can hear something like 10% of the P pickup from the J, whats the best way to figure out if its the pickup or the pot?

I don't know what the DC resistance is of the pickup, so maybe someone else can help with that.
If you're handy with a soldering iron and an ohmmeter:
1. Take the bridge pickup's pot completely out of circuit by disconnecting all leads to it and its metal cover.
2. Measure its resistance (ohms) across the two outer soldering lugs. It should be 250,000 ohms, +/- 20% (or so).
3. Then measure the pot's resistance from one of the outer lugs to the center lug, sweeping the control back & forth. You should see a relatively smooth swing from zero ohms to 250K ohms.
4. Repeat step 3, only between the center lug and the other outer lug. The result should be the same.
5. Check for resistance between each lug and the metal body of the pot. There should be infinite resistance, meaning that there should be no connection at all with the pot out of circuit.
6. Disconnect the existing leads at the jack and connect the bridge pickup directly to it. If the pickup is healthy, you should be able to get a respectable volume from your amp.
7. If someone can come up with the pickup's DC resistance (out of circuit), measure yours across the leads. The values should be within a couple hundred ohms of each other. Note that this can be kind of tricky and a moving target due to differing ages of the pickups that were measured, so don't worry about a relatively small difference.
HYPOTHETICAL OTOH, if I were to measure my SB-2's pickup and it were to read 8.3k ohms and yours read 6k ohms, then you would probably have a damaged pickup.
