Not necessarily. Depends on which side of the cutoff the alternator is hooked to. If it's attached to the battery side or to the pos batt post, the car will shut off but the alt wire will always be hot. If it's attached to the car side, the car will continue to run because the alternator is supplying the power. By the way, when this occurs, the alternator voltage will be unregulated and will go to 20+ volts when you turn off the switch.....ever been told you could test an alternator by unhooking the positive battery cable? That's why you shouldn't. It'll supply 20+ volts to the entire car if the alternator is working......
I'd think the small posts on the switch would be independent of the big posts on that kind of switch or you could use a relay
