I'd say a lot of waterboxer vanaogns are not getting 14 volts to the
battery.
I'm checking an 85 right now ..
it's got 13.8 at the alternator, only 13.4 at the battery.

on m own 85 I added an extra battery cable ...that helped get
measured-at-the battery charging voltage closer to the voltage measured
at the alternator.
VW made the main battery cable bigger in 86 of course..bad habit of
theirs ...upgrade to what it should have been in the first place as the
year models progress.
