Outdoor lighting problem.
Below is a picture of a connector of one of my low voltage lighting runs. Its a long run, so I ran a wire to the center of the run so power will be evenly distributed. This is the second time I found the connector in this condition. At first I thought it was water intrusion, but this has a slight burnt smell. Could water do this, a short, high resistance in the wire or just poor connectors? Its a 300 watt transformer, and the lights add up to less then that.
