I spent the past week testing all 67 sirens in the county, one by one. 13 were found to be inoperable. 2 of which just had a rectifier and new service disconnect installed and are waiting for the power company to bring 240 to them. Another 2 had blown fuses. 3 had fried radios, and the rest had some sort of battery issue.
