low oIl PreSSure SYSTeM
Some engine applications may be equipped with a low oil
pressure switch (see Figure 9-9). The switch is a normally closed
type, but is held open by engine oil pressure during cranking
and running. Should engine oil pressure drop below approxi-
mately 0 psi for any reason, the switch contacts will close. With
the switch contacts closed, the following will occur:
• A low oil pressure indicator will turn on and glow as power
is available for its operation.
• The closure of the switch contacts will connect the primary
ignition circuit to ground. Ignition will terminate, and the
engine will shut down.
NOTE: Some differences may exist between low
oil pressure systems. Refer to the electrical schematic/
wiring diagram in the Owner’s Manual for the specific
application using this engine.
