PURPOSE: A circuit for warning an action of a circuit breaker is provided to easily inform a driver of a state of a start electromotor by lighting on a lamp when the start electromotor is overheated and the circuit breaker is operated. CONSTITUTION: A circuit breaker(1), a lamp and a resistance are each connected in parallel, and the size of the resistance is set up in order of circuit breaker, lamp and resistance. In the normal operation, most of the current flow through the circuit breaker(1) by the resistance difference of circuit breaker, lamp and resistance, so that the lamp is turned on. On the other hand, when the circuit breaker is turned off, the current flows through the lamp by the resistance difference between the lamp and the resistance, and the lamp is turned on. Herein, the resistance is connected with the circuit breaker in parallel so the lamp as not to be turned on when the circuit breaker is on. Accordingly, since a user thinks that the circuit breaker is out of order if the key switch is turned on until the inner temperature drops, the user confirms the normality of the vehicle.
