Tested lighting system and all lights. Found 2 completely broken path lights along driveway, and 2 additional path lights not working. Also found that the transformer circuit breaker kept tripping, from driveway wire run. I fixed wire connections on both broken path lights and also on a 3rd path light not working, which was causing breaker to trip immediately. I also replaced a worn out mr16 bulb for front left Japanese maple tree. Retested good. Customer declined replacing any of the broken path lights at this time. Note: due to the plow damage, it is possible that the transformer circuit breaker could trip again. If that occurs, we will need to perform extensive electrical troubleshooting to locate the damaged wire.
