Troubleshoot several lights not working, Found a total of 10 lights not working upon arrival: 8 front left foundation +2 front right foundation. After extensive troubleshooting, determined that a wire was bad running directly through front left birch tree (photo). I replaced a section of wire in front of the tree. Also found several corroded or broken wire connections and replaced approx 3-4 wire connections, front left path light by garage, and front left island walkway boulder area. Adjusted invoice lower to reflect actual work performed, and created another estimate for additional work needed. Determined that 3-4 uplights need to be replaced, and additional wire connections repaired. Customer not home upon completion today, spoke to on phone.
