If the sender on the side is grounded, the light blinks.  If the rpm
is over 2000 and the sender under the water pump is *not* grounded,
the light blinks and the buzzer sounds.

The one sender opens at 0.3 bar; the other one closes at 0.9 bar.  If
a 1.8 bar sender gets in instead, will cause false alarms.  But the
fact that the alarm goes off at 3,000 rpm and not 2,000 is worrisome
(to me, the non-expert) because the pressure should be higher as the
rpm goes up.
