ーズ１５が切れると、警報器１４の作動も不能となるの
で、スイッチ１３を操作してみて警報が出ないときには
、電磁ソレノイド８が故障した可能性が高いものとして
点検してみる必要がある。Also, if an overcurrent flows and the fuse 15 is blown due to a problem with the electromagnetic solenoid 8, the alarm 14 will not be able to operate, so if the alarm does not come out when you try operating the switch 13, it is possible that the electromagnetic solenoid 8 has failed. It is necessary to check it to see if it has a high level of quality.
つまり、警報器１４を電磁ソレノイド８のトラブルチェ
