How to connect the starting power supply of diesel engine?

Two wires from the flywheel generator are connected to the voltage regulator. One grounding end of the voltage regulator is connected to the fire lock, and there are two ignition locks. One is connected to the starting relay, the other is connected to the power end of the starting motor, and the rest is the positive pole of the battery connected to the power end of the starter. One grounding is good

Ensure that the three wires on the ignition lock are connected to each other when starting, the wires from the voltage regulator and the starting motor are connected when running, and it is good to ensure that the three wires are not connected when the engine is turned off

Of course, if you want the ignition lock to have the flameout function, you need to add additional parts

That would be more troublesome and unnecessary
