Engine Oil Pressure Switch (Model 04580)
g289630
Figure 78
The engine oil pressure switch is located on the right side of the engine near the
oil filter. The oil pressure switch is a normally open switch that closes under
engine oil pressure.
The condition of the engine oil pressure switch is monitored by the T1: Primary
controller. If the oil pressure opens (low oil pressure) for more than 10 seconds
while the engine is running, the controller will de-energize the engine control
circuit to stop the engine.
Testing the Engine Oil Pressure Switch
Refer to the
Kawasaki FS481V Service Manual
for information regarding engine
lubrication system testing.
The engine oil pressure switch and its circuit wiring can be tested as a T1:
Primary input using the InfoCenter Display; refer to
for Troubleshooting (page 3–39)
. If testing determines that the switch and circuit
wiring are not functioning correctly, proceed with the following test procedure:
1. Park the machine on a level surface, lower the cutting units, set the key
switch to the O
FF
position and remove the key from the key switch.
2. Locate the engine oil pressure switch on the engine and disconnect the
wire harness connector from the switch. Check the switch and the harness
connector for damage or corrosion and clean or repair as necessary.
3. Connect a multimeter (ohms setting) to check the continuity of the switch:
A. With the engine off, there should be no continuity between the switch
terminal and the metal switch body.
B. With the engine running, there should be continuity between the switch
terminal and the metal switch body.
