Safety relay change( Add time delay function)
Alternator "L" Key "C"
*** 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
GND Safety lever
start motor. To prevent this, we add the time delay
function at safety relay.
