The problem appears less on the 88> 200, cuz audi changed the cable routing
(no splice, dash comes from 2 feeds at the battery).  That said, you can
easily ck if you have a problem.  Ck battery voltage vs a/c head voltage vs
alt voltage.  Less than .5v is good.  More than .5 volts, I put in an aux 2
or 4 guage wire from the alt to the battery direct.  This usually puts the
A/C head voltage within .2 volts of battery.  I don't find this problem to be
unique to any particular chassis thru 1991.  As of 1992, audi seemed to
address the problem (or they just aren't old enough yet).

The problem is the audi wiring is prone to corrosion and resistance.  When
this happens you get 100% alt output 100% of the time.  This causes premature
failure of the charging system.
