2. When the battery (+) side is connected to terminal 1 and the (-) side is connected to terminal 4, and the main switch is turned to ON, check if battery voltage is output between terminal 5 and the ground until the main switch is turned to OFF.

Next, when the main switch is turned to OFF, check if the battery voltage that was output between terminal 5 and the ground becomes 0 V.
