Thanks, Donald,very good! Starting to wonder if I was nuts. Most old
VeeDubs with some miles on them had this quirk,which I never considered a
problem. Went out to the garage and found the Bently book,revealing no
unusual oil pressure light circuitry. I'm sure it's a connection problem,
due to the increased circumstances when the weather is moist.
Goodnight,typ II freaks:
