This is a multiple string LED prelit Christmas tree. Why do the lights fail to light when a light keeper pro shows voltage throughout the tree?
Hi, Just verifying that you have double checked the electrical connections. Not sure if this is applicable to your particular tree but here are some instructions for a Winterberry tree that may be of some help. ‘‘a) End Plugs - Fully insert the plug from the top pole into the end connector near the top of the lower pole. Continue down to connect the bottom if your tree has (3) lighted section. b) Connectors – First find the 2 yellow CONNECTOR cord tags located between each section. First align the 2 pins and flat on the connector and then fully inserting into the other connector. Fully screw on the cap to secure together. Repeat if your tree has (3) lighted sections. NOTE: Reattach any loose bulb by fully inserting into an open lamp socket Your winter Christmas tree is now assembled! 9.To illuminate find and unhank the long lead wire from the bottom lighted section. Fully insert the plug directly into a working GFCI outlet or an outdoor rated extension cord. 10.Some Models have a dual color, 4-function control box. The functions are: Steady White, Steady Multi, White & Multi Color Change and Off. 11.Please check your tree for any loose, unlit or damaged bulbs. They must be replaced promptly in order to maintain the performance and life expectancy of your pre-lit tree.’’
