But given your initial narrative, the driver smelled smoke under his dash. I just took a quick stroll through some of the car's wiring diagrams, and there are 'hot at all times' notes all over them at DC supply points feeding stuff in the dash. It's really difficult to see how disconnecting the field of the (internally regulated) alternator would make any difference whatsoever, with so many different 'always hot' supply points from the battery itself. In any case, assuming the driver turned off the ignition switch, the alternator wouldn't be a source of power, and the feeds *to* the alternator are protected by fuse links. So...If I were an NTSB investigator, I'd be leaning more toward not having a master contactor to disconnect the battery.
