I tested all the lights before I put them on the tree. 2 strand worked perfectly and the third strand had a "dead" section. So, I started at the top with the ones that worked. With the help of Marty and the almost 6 extra inches of height, we got the angel on the tree and started winding the lights around the tree. The two working strands didn't quite make it to the bottom of the tree but I figured it would be ok to use the partially working strand around the bottom. We got them all on and were so excited to light the tree up. I plugged it in, stepped back, and said "WTF?!?"
The angel is lit. The partially working strand worked out perfectly around the bottom. In between the angel and the partially working strand, NOTHING...NADA...ZILCH. That's right folks. The two strands that were fully lit on testing were fully dark on the tree. Obviously, electricity was making it through...light at the very top and at the bottom. I checked all the connections and one of the two previously working but now dead strands of lights decided to join the brightly lit crew again. Nothing I tried got the last strand working so I guess I have to go try and find a strand of lights tomorrow.
The gremlins have taken over and so far they are winning.
