Wierd oil problem

[smithma7 at yahoo.com (Mike Smith)]

OK, as I left work last night, I tried the rev test.  I started it, let it run for a moment and then brought the RPMs up to about 2750.  Sure enough, 3-4 seconds into it, blink and buzz.  PCB or grounds or what?

The oil warning light does not sense oil level. It senses oil pressure. You
can be very low on oil and still have adequate pressure. Of course there is
a limit! (no oil, no pressure!)
Aside from an actual oil pressure problem, the sensors can fail, you can
have loose connections or the oil pressure PCB can fail or have intermittent
failure. I've experienced the PCB intermitent failure that appears to be
ambient temperature related.
The PCB is not cheap at $38, but that seems to generally be the problem with
an intermittent oil light/buzzer.
Aside from replacing the PCB, I installed an oil pressure gauge so I know
what the pressure is.
