We have three strings of LED Christmas lights in series around our porch. Last night, my wife noticed that the middle string in the series was out. The two strings on the each end were fine. My grand daughter said "granpa, they're not out, just dim". I brought them in, and she was right. You can hardly see the light in the bulbs. All LEDs are lit, but very, very dim. I have no idea of how these are wired. I haven't done testing yet. Any suggestions?
