Jeff,

The "Usual" problem with Vanagon analog clocks is ... there are two
100uf capacitors therein that get leaky (electrically) over time.  The
symptom is erratic running ... often when it gets cold and/or damp out.
  The fix is, of course, taking the clock apart and replacing the
capacitors.

I would've thought your '86 weekender would have had the digital clock
and a tach.
