OIL PRESSURE INDICATOR SWITCH

3.11

 

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 3-24.

 

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.

 

OIL PRESSURE

 

See 

Figure 3-113.

 The oil pump is non regulatory and deliv-

ers its entire volume of oil under pressure to the oil filter
mount. When an engine is cold, the engine oil will be more
viscous (i.e., thicker). 

When an engine is operated at high speeds, the volume of oil
circulated through the oiling system increases, resulting in
higher oil pressure. As engine speed is reduced, the volume
of oil pumped is also reduced, resulting in lower oil pressure.

To check oil pressure, use OIL PRESSURE GAUGE (Part No.
HD-96921-52B) and OIL PRESSURE GAUGE ADAPTER
(Part No. HD-96940-58). Remove oil pressure indicator
switch and insert pressure gauge fitting.

Ride motorcycle at least 20 miles (32 km) at or above
50 MPH (80 KM/H) until engine oil reaches normal operating
temperature. At 2500 RPM, oil pressure will vary from 10-
12 psi (69-83 kPa). At idle speed (950-1050 RPM), oil pres-
sure will vary from 6-8 psi (42-55 kPa).

).

Flickers at idle.

 

●

 

Incorrect idle speed. Malfunction-
ing or improperly installed check
valve (see 

3.15 OIL FILTER

MOUNT

).

Does not glow 
when ignition 
is turned on 
(prior to oper-
ating engine).
