Hi Guys
16+ volts is to high, you are in danger of boiling the battery when you have
that much output, you are looking for figures around 14.5-15 Volts. I would
suspect a regulator fault with 16+ volts.
I hope it helps.

I bought a multimeter yesterday and checked the battery, the results
were:

engine not running                                         - 12.9V
engine idling, no extras                                   - 16.9V
engine revving, heater, lights, wipers, stereo, indicators - 16.5V

Which seems to suggest that the battery/new alternator is very healthy,
although the 16V readings were higher than I expected.  Although this
morning driving to work with lights/heat/stereo on the car seemed to
struggle at around 3000-4000rpm (after that I cut the
lights/heat/stereo).  I don't know if this is another problem(clutch
slipping maybe?) or if it suggests that the alternator wasn't the problem
and my battery is getting drained because of another problem somewhere
along the line. Or I might just be being paranoid as I often do after
something breaks on Saskia, I seem to notice any oddities about the car
and instantly attribute it to whatever the last problem I had was!  I
wish I didn't worry so much!

cheers
