First of all, thanks to everyone who responded to my question!

Further evidence of my ignorance, I'm afraid:

I pulled my Westy to the back of the house to work on it, called a local
parts guy to see if he had an alternator in stock (he did: $170!!), put
on some work clothes, and prepared for an evening of getting to know my
Westy a bit better and dirty...

...only to discover that the little blue wire (to the alternator warning
light) connector had come loose.  I re-connected it, and - upon starting
the engine - found that the alternator warning and oxygen sensor LEDs no
longer came on.

Now I'll try to fix the blinking temperature warning light...
