PURPOSE:To facilitate the cooling operation, reduce the size, and prevent the breakdown of a starter motor by allowing a blower switch to work as a cooling engine starter key concurrently and driving a starter motor for a fixed time with this switch on. CONSTITUTION:When the ACC circuit of a travel engine key is turned on, a transfer knob 12e is turned on to set the wind quantity. Then coils 2a, 3a are energized, and a cooling engine ignition circuit and a timer circuit 4 are turned on and the connection between terminals 5b, 5c is closed through the closure between terminals 3b, 3c. Thereby, a stater motor 7 is started for a preset time of the timer circuit 4, thus generating electricity with an alternator 8. After a predetermined time has elapsed, the starter motor 7 is stopped, the connection between the terminals 5c and 5d is closed as a result of charging by the alternator 8, thus energizing a cooling load 10 and a cooling blower motor 11 for cooling. Thereby, the size is reduced and the breakdown of the starter motor can be prevented. |
