*** During the air bleeding procedure from fuel line, We need more cranking time to start engine. But at this situation, new alternator produce a little bit higer voltage at the termianl “L”. So this voltage deenergize safety relay and interrupt start motor. To prevent this, we add the time delay function at safety relay.
