Crossover help?

I don't see your system. Look at this thread,https://forum.audiogon.com/discussions/tweeter-blown-or-crossover-how-to-check

I searched and saw picture of upgrade, you have circuit board, per grannyring likely damaged pad or trace. Solder pads easily damaged in removal of original components, need proper desoldering equipment, don't force anything. Believe me I know from experience.

Above if you're 100% sure drivers working.

I used a sucker and wick, the tracks are pretty robust.

I get a a bleep up to and away from the cap, can't test the cap but neither new or old refitted made any difference.

I'll play around again tomorrow see if I can find a break.

Really struggling with this one.

Any idea what reading I should get from the coil?

Its showing 0.9 .71mm

Did you read that thread I mentioned, I find it hard to believe your tweeter not fried or board damaged. You have to make sure you haven't damaged voice coils, pretty fragile. Multimeter readings often of no use when everything in circuit. You have to put battery across speaker terminals, or send signal directly to tweeter bypass entire crossover, remove all crossover wires from tweeter terminals and test. If tweeter working, circuit board bad. Unless fried inductor.

You may have to find local tech or send board back to PMC. Too difficult to troubleshoot by forum. I just have to believe you've fried something.

A little late perhaps but here is how you do it.

Notice the last few pictures are the crossover upgrade. The last one is annotated with measured values and the wires that attach. There are also pictures of the original xo that I didn't post but are the same, multiple pictures including one annotated with all values and connections. Also in addition to this the parts were physically labeled, both the wires inside the speaker and on the boards. All the wiring is point to point and every part on the original was measured individually. This is how you do it when you want everything to work right the first time. 

If you take real clear pictures from different angles showing clearly all the solder joints we might still be able to figure this out. That is your best bet, because no manufacturer is going to do anything but sell you another crossover, and probably not even that. If you were making speakers and a customer called saying he screwed it up would you trust him to not screw up installing the replacement? I wouldn't. So figure it out and fix it.

If there is a circuit board then clear pictures of both sides. Circuit board traces are pretty thin, it is real easy to burn one out if you're not skilled at soldering.
