Well, I changed out the voltage regulator and did a little emery cloth work on the alternator terminals (they were greenish-corroded looking). Took it out for a spin, and did not get the charge light to come on. Turn signals worked throughout the drive, so perhaps if I'm lucky I've fixed it. Then again, yesterday was the first day in quite a while in which it hasn't been raining, so perhaps that is what really affects it.

I'm still puzzled by the link between the charge light and the turn signals. Is it possible that the turn signal relay just won't operate at standard 12 volts, and only operates at the higher charging voltage? Where is the turn signal relay on a 190D, anyway? Is it up under the dash behind the kick panel, I suppose?
