I'm having a discussion about wiring the Master Switch in a Miata. The NASA CCR specifies that "The switch should shut off the motor and cut all power except to the on-board fire system, radio communication,and any other life support / medical device." The SCCA GCR does not have the requirement that the master switch shut off the motor: "The master switch shall be installed directly in either battery cable and shall cut all electrical circuits but not an on-board fire system."
It seems to me that the master switch *should* turn off the engine. Is this an oversight in the GCR?
