Voltage and suspension questions

["J. Smethers" <smethers@fast.net>]

Audi'tes,

I replaced the voltage regulator on my '86 4KCSQ (97K miles) this morning,
hoping that it would solve the problem of voltage drops when I run a lot of
electricals in the car.  One of the brushes was toast, but the replacement
did not do the trick.  The ground looks okay also.  Am I correct in thinking
that there should be no change in the voltage (as measured by the center
console volt. meter) when the car is under a heavy electrical load.  I
notice it especially when the engine fan kicks on.  I'm worried that the
alternator may be dying.

Also, had the rear CABs replaced yesterday.  The car toes right now so I
know an alignment is in order.  But I also notice that the car does not feel
as solid as it did before.  Last night, I drove the car on a wet
snow-covered highway and I could not get it to stick.  It felt real loose in
the back, like never before.  I am only two months new to the quattro
experience, so maybe this is common with this road condition.  Would the
center diff. lock help here, and if so how fast and far can I drive with the
center diff. locked.  Even this morning, I shimmied on wet train tracks.
The car feels real loose - HELP.
