Hows it going, have a u5000 neckboard thats already had a cap kit and yes all are installed correctly. C507, c530, and zd500 all read shorted, however completely out of circuit they read perfectly fine. I cannot find anything else wrong at least not enough to cause that so my thoughts are maybe u500, as almost everything on the neck board comes or goes from it. Any was to test u500 with my fluke or any other suspicions? I have to order some u500 LM whatevers. Cheers!
