Did you make that cable using CA-0446 cable from Best-Tronics? If so, open the connectors and trim back that thin clack layer on the dielectric. It looks like it should be an insulator, but it conducts current. It can cause the problem you experienced.
Thanks! I will check out my no doubt sloppy soldering. LOL.
It is from LAKE CABLE AVB20UGC 20 AWG low capacitance wire.
