Since the switching device is disconnected, the power can be supplied from the AC generator to the power supply, and the switching device that the pool switches from the AC generator can be used for universal starting relays. Because there is no special system It becomes cheap. In addition, the system can be compacted by sending Gong Erji, so the system can be compacted. X Electric is shared with the starter motor, and the control device is electrically connected to the main switch due to the scope of patent applications Nos. 5 to 7. The electric power supply device is provided with a capacitor and an ant generator side in the circuit from the main switch to the battery, and the self-powered first diode to prevent backflow is also set in the circuit to the control device. The main switch of the generator H is connected to the second diode of the AC power generation countercurrent. Therefore, by turning on the power of the main :: clothing, it can prevent any one of the motor from supplying power to the control device. It can be sent from the battery and the AC will not flow into the battery. Therefore, even if the power generated by the AC and the motor is small from the AC generator to the control, the startability of the engine can be controlled, so that the control device can be installed, can be maintained well, and can be borrowed! ;:; Force: The reliability of the device. The current direction of the device is always “fixed,” = Guard 2: The motor flows to the control element number. 1〇 Vehicle (locomotive) 11 Handle 12 Start switch 13 Main switch 14 Front cover Page 22 C: \ 2D-CODE \ 90-12 \ 90123463.ptd 538575
