LED Repair and Mods A bit more complicated than incandescents but doable. By Dennis Eaton This presentation was part of one of my Christmas Expo classes in July. I wanted to share it with PlanetChristmas Magazine readers. Repairing or modifying LED strings is definitely possible but you need to be handy with a soldering iron as well as cutting/splicing wires and components. I gave a slideshow presentation at Christmas Expo that looked really good on the big screen. With the help of some editors at PlanetChristmas mag-azine, we’ve tried to present this on the small page. Safety You should never take safety for granted, especially when working with electricity. • Have a good working knowledge of elec-trical power and the potential injury that is possible • Utilize GFI circuits for testing and repair of your string of lights • Make sure to have a working multi-meter and feel comfortable with its use • Be extremely careful, it is very easy to dam-age LEDs and worse yet, YOURSELF The Tools for Repair • LED Keeper and Bulb Replacement Pods from Ulta-Lit Technologies, Inc. in Glenview, IL • Markers • Wire Clippers – Side Cutters 20 PlanetChristmas | September 2014 • Wire Strippers (smaller diameter) • Connection options – soldering, wire nuts or crimp connectors • Replacement LEDs – fixed and socketed The Repair with LED Keeper 1. Check the LED light string for cuts, nicks or abrasions. If everything is OK move to the next step – if damage is found make repairs before proceeding. 2. Check fuses at the male plug side with your multi-meter set on continuity set-ting. If everything is OK move to the next step – if bad replace with the correct fuse and then move on to the next step. 3. Check for damage to the male spades coming off the plug (loose, bent, twisted), the spades should be snug in the plug body. If loose replacement might be needed. 4. Plug the string in – find the bad or non-lighted section of your LED light string. Strings can have one circuit/lighted sec-tion with two to five circuits/lighted sections. 5. Once you have found the section that is out then mark off the section or sections with tape, marker, clothespin or a gullible family member.
