(KLZA)-- A failed lightning arrester  and a broken switch were the issues causing a power outage on a circuit serving the east side of Stone Street and west side of Harlan Street in Falls City Wednesday morning. 

Falls City Utility Superintendent Ray Luhring said it's difficult to find the issue with a lightning arrester and power was on and off while the city line crew searched for the problem.

Once an issue is found,  power is shut off to protect the workers while they repair the damage.

The outage was in what the City calls Circuit 4, which is one of the circuits included in the plan for major upgrades to the power grid in downtown Falls City.
