Surprised the AAA wouldn't measure the battery voltage?

But as others said it doesn't sound like battery/alternator. If you ran down the battery in your first event to the point where the DME gave up (~ 9 Volt) there is no way it recovered to where it could turn over the engine with the starter. You would have gotten nothing, not even dash lights....

If you really smelled something electric burning I'd focus on the DME under the drivers seat. That or the ignition switch might have overheated from a fault and that's what you smelled. To smell a frying alternator takes A LOT in a 911. I'd say its unlikely unless that thing is on fire. Remember the engine fan drives air down the engine guiding any smell right out and away.
