I've got an issue I cannot figure out for the life of me. I've got a NMO mount mounted on the front fender of my pickup. I ran a ground strap from one of the bolts to a bolt on the firewall. I usually have my WS1040 plugged into my truck's stereo using the AUX Jack. Whenever I used my mag mount, the audio would play through both sides of the truck. But whenever it's hooked into the NMO, it cuts the audio out on one side. I was thinking there was a short in the wire or the mount. I checked for continuity between the center conductor of the RG58 and the ground strands and there was no continuity. I recently had a BNC connector crimped to the cable and I'm thinking maybe the guy who installed it, shorted the ground with the center conductor. But if that was the case, wouldn't there be continuity? I can't figure it out and it's giving me a headache.
