3.14 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 Table 3-22 .
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.

PROBABLE CAUSES OIL PRESSURE
SIGNAL LAMP
Stays on at speeds
above idle • Empty oil reservoir
• Grounded oil switch wire
• Malfunctioning signal switch
• Diluted oil
• Malfunctioning or improperly
installed pressure relief valve
Flickers at idle • Incorrect idle speed
• Malfunctioning or improperly
installed pressure relief valve
Does not glow
when ignition is
turned on (prior to
operating engine) • Malfunctioning signal switch
• Malfunction in wiring
• Burned-out signal bulb
• Dead battery
3. Assemble banjo bolt (3), washer (4), oil pressure gauge
(1) banjo fitting and second washer onto adapter and
tighten snugly.
4. Temporarily secure oil pressure gauge and hose to
motorcycle frame with cable straps. Make sure gauge and
hose assembly do not interfere with normal operation of
the vehicle. Start engine and ride motorcycle at least 20
miles (32 km) at or above 50 mph (80 km/h) to allow
engine to reach operating temperature of 180° F (82° C)
.
a. At 3000 RPM, oil pressure will vary from 20-28 psi
(138-193 kPa).
b. At idle speed (1050-1150 RPM), oil pressure will vary
from 10-16 psi (69-110 kPa).
