PURPOSE:To simplify the structure of a controller and improve reliability by taking-out a starter motor from between a plurality of batteries and installing a short-circuit current intercepting means between the connection terminal and the starter motor. CONSTITUTION:A multifunctional starter 1 is constituted of a main switch 2, starter motor 3, reduction gear 4, and a hydraulic pump 5. A switch 28 for driving an auxiliary rotary machine is installed between a battery 24 and the starter motor 3. A fuse hole 32 is formed between an always opened contact 30 and a low-voltage terminal 24b. When a key switch 21 is erroneously closed during the operation of the auxiliary rotary machine, an auxiliary switch 22 is operated to open a contact 25, and the excitation of a coil 29 is released to open the contact 30. Since a main contact 6 is closed, high and low voltage terminals 24a and 24b are short-circuited. Therefore, the structure of the controller can be simplified, and reliability can be improved. |
