I have also had some that worked for years on end. But the ones I had trouble with was usually due to moisture. I suppose they would also be vulnerable to temperature. Is the coupler in a very insulated environment? I had one in my garage go bad. If at all possible, I would highly recommend replacing the entire run with a single cable. You can test this by just running a single long cable from end to end along the ground for a few minutes. It will either work, or it won't. -wes _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
