Rotation detection
1) Let's suppose that the operator turns the key to the start position while the engine is running.
2) In this case too, the turning signal comes from the alternator (10) as discussed before. In other words,
the auto release relay (9) remains off.
7. Function of low-voltage detection
When battery voltage decreases down below 5 to 6 V at the cold start, this low-voltage detection func-
tions to turn on the transistor and so turn on the auto release relay unconditionally.
