Sorry meant to reply to this with meaningful measurements but on my way to work today the regulator/alternator quit fully. I drove about 100 miles on pure battery. Lets just say, it was not pleasant at all on the return trip.

Nothing likes to run well at 10V.
The glow plug relay was confused at 9V and decided to join the party
System voltage dropped to 6V and the climate control decided to leave the blower on and not much else worked beyond that.

More fun was the rain and darkness. When I got home I was pleasantly surprised to see my lights still giving off light. At least I was visible on the road still.

I've ordered a new regulator. I'm mildly certain that I damaged the brushes on the existing one when I clocked the alternator. OH well. The 190 is put back into service for a few days.
