Hello to all-

I just wanted to thank everybody for their help regarding my oil light
problem on my 87 Vanagon.  After lots of troubleshooting the problem was a
faulty voltage regulator on my alternator.

I installed a new voltage regulator/brushes kit on my alternator a couple of
weeks ago.  It checked OK after installation.

Last night after more touble-shooting (trying your suggestions) I measured
the output voltage of my alternator...  It was 16.5 VDC at idle and 18.0 VDC
at 2000 RPM...

I put the old one back in and no more oil pressure light!  I'm sending the
faulty one back for replacement.  I'm getting pretty good at removing the
alternator...

Many thanks.  I hope this info can help somebody else later.
