Howdy volks,
Another newbie here.   4 year owner of an '86 Westy. This list is great.  Had
I known about it a year ago I would have a few more dollars in the bank.  I
got a little ambitious with fixing it myself and ended up chucking my 106 K
2.1 liter engine for  a factory rebuild.
I have about 5000 on the rebuild and have had the same oil light and buzzer
problem as mentioned in earlier posts to the list.   The oil pressure light
and buzzer comes on, usually after highway driving when slowing down for a
stop or a slower speed zone.  A push  on the clutch and a rev of the engine
silences it until the next stop.  It rarely, if ever, happens when driving in
town and isn't a problem when idling. I don't have a tach on the dash, just
the stupid clock, but I would estimate the problem occurs between 2000-3000
rpm. I ran the wiring tests for the .3 and .9 bar switches as indicated in the
Bentley and the wiring to the dash tests OK.  I have replaced the .9 bar
switch to no avail.  Going to 20W50 from 10W40 silenced the buzzer  for night
time drives but in the heat of a summer day she hit me again, as she usually
does, when slowing to pass through Moundville, AL(Joel Walker should know this
place.)

Can the voltage regulator effect the performance of the dynamic oil pressure
sensing unit?

I am suspecting a faulty dynamic oil pressure sensing unit but the voltage
regulator is probably cheaper.

What do y'all think?
Thanks volks,
