P-J wiring help

I'm rewiring an old Ibanez Roadstar with P and J pickups, and I've clearly opened up a can of worms. My original plan was to replace the awful sounding P pickup, so I got a Dimarzio DP122 set, and put those in, and all as fine. But it had a blend/volume/tone setup, and the blend was nowhere close to even hen it was on the center detent. So I figured I'd switch to a V/V/T configuration, and I bought two new pots for the volumes.

I've followed the dimarzio wiring configurations, and everything appears to be wired correctly, but I'm having two problems:

1. The bridge (jazz) pickup isn't working at all. I've tried two pickups and I don't get anything out of either of them. Obviously, this problem can't be solved without seeing it, so I'm going to troubleshoot a little more and then post a picture tomorrow if I can't figure it out; but in the meantime, I'm wondering if it could possibly be related to problem #2:

2. The volume for the neck pickup mutes when it's on full. If I back off just a hair, I get full volume.

I suppose the answer to both of these issues is that I got bad pots. Is there a way to test pots with a voltmeter or something?

thanks!

A multimeter set to measure ohms is needed. Zero ohms wide open is the target or near to it say .05 ohm. Anyway, are the knobs push on? I had an issue with a CTS that died when I pushed the knob on. I pulled it up to remove it and the pot is fine now. The wiper ARM must have deformed and was not making contact with the resisting strip inside the pot. Pulling it back up fixed it. The pot works great now. As for the muted at 100% pot it may have some gunk on it from manufacture, try cleaning with contact cleaner.
