OIL PRESSURE INDICATOR SWITCH
GENERAL
The oil pressure indicator switch is a pressure-actuated dia-
phragm-type switch. When oil is not circulating through the
system or when oil pressure is low, spring tension holds the
switch contacts closed, thereby completing the signal light cir-
cuit and causing the indicator lamp to illuminate.
OIL PRESSURE SIGNAL LIGHT
The oil pressure signal light turns ON when:
•
Ignition switch is turned on prior to starting engine.
•
Oil is not circulating through the running engine.
•
Oil pressure is abnormally low in the running engine.
•
Engine is idling below 1000 RPM.
The oil pressure signal light turns OFF when:
•
Oil is circulating with adequate pressure through the
engine running at 1000 RPM or greater.
Troubleshooting information is listed in
.
NOTE
If the ignition is turned back on immediately after the engine
is stopped, the oil light may not turn on right away because of
oil pressure retained in the filter housing.
