If you turn on the key switch and put a voltmeter between the wire to the o/p
sensor and ground, there should be 12V approx there. If there is voltage and
you ground the wire, the buzzer should activate. If there is no voltage check
the other end of the wire and chase the problem from there. The
Understood Bill, I know the buzzer works and that it has power to it. "
ONLY" I will ground the lead to the switch and see if it sounds key
position on but engine off. It it sounds that tells me the wire and led and
buzzer is good and the switch is faulty.
Thanks again guys.

But it does eliminate the buzzer itself as a potential problem...

Careful about that assumption. According to the Yanmar rep. that I spoke to
at the Annapolis Sailboat Show, that switch only tests the light and
buzzer by supplying power to them. It DOES NOT check the entire circuit to the
sensor/switch.

Yup. That's what I though.

True statement. I suggested earlier that if it does not sound when the wire is
grounded the problem is elsewhere.
A resistance/continuity check across the sensor will quickly tell if it's
faulty. No oil pressure should yield a direct short.
