SDA-2 Trouble shooting

I have been troubleshooting my SDA 2's for a week with no resolve.

I can't get my stereo array tweeter in my left speaker working and I know that tweeter works.

I've removed all of my polyswitches and just tonight checked all of the readings between the IC pins and +/- terminals on the speaker, with all results showing in spec according to the sticky PDF here. Does this mean the XO's are ok because the ohms checked out?

If not, what would be my next point of attack? Would anybody know if the Polk CS can still check old SDA XO's?

Thanks in advance!
Jason

    I am wondering same sort of thing. Is my interconnect working. hmmmm. I was going to call polk today and see if there is any support. I am not getting any readings w/multimeter.

    Have you tried putting the left tweeter in the right speaker and vice versa?
    Can that be done?

    Just thinking out loud.

    If the tweeter is good and you aren't getting any sound, then you've lost conductivity somewhere. Following the schematic, go step by step from where the wires connect to the speaker to the appropriate binding post and IC pins. Then, make sure the IC pins in the opposite speakers are connected as they should be.
