Abstract
A failure diagnosis system according to an embodiment includes a first power line, a second power line, a first main contact, a second main contact, a first electrical component, a second electrical component, and a control device. The first electrical component includes a first terminal electrically connected to a second part of the first power line and a second terminal electrically connected to a third part of the second power line. A state of the first electrical component is to be switched in a case where a voltage is applied between the first terminal and the second terminal. The control device is configured to determine whether an abnormality of the first main contact exists or not based on output of a control instruction relating to the first main contact and the state of the first electrical component.
