Sounds like the voltage regulator has packed up in the alternator. Get some charge into the battery and read this http://www.omegaowners.com/forum/YaBB.pl?num=1225724099
Then paperclip it for codes stored as you say the EML illuminated and car went into "limp mode" http://www.omegaowners.com/forum/YaBB.pl?num=1189022687
I assume you`ve checked the aux belt and tensioner pulley :question

I would suspect the alternator voltage regulator has died. What voltage did you see when you revved the engine?
If it blew a headlight bulb it could also have blown the ignition (alternator really)  warning lamp.
The battery could well be faulty as well, if an internal joint in the battery fails it means there is nothing to damp the alternator output which can be a cause of regulator failures. On the other hand, if the regulator fails the battery is overcharged and vents off all its electrolyte which cant be replaced as they are sealed.

Where are you?  I have 4 or 5 Alternators kicking around.  I'm in Bristol.
