TROUBLESHOOTING AND ELECTRICAL SYSTEM
6. Place a jumper wire on the terminal of the low oil warning light where the blue/white wire (w41) was removed.
7. Touch the frame (ground) with the remaining end of the jumper wire.
8. Turn the key switch to the ON position. The low oil warning light should illuminate.
9. If the low oil warning light does not illuminate when the key switch is in the ON position, check the 18- gauge
purple wire (w40) for continuity between the terminal at the low oil warning light and the 18-gauge purple wire
(w126) at the key switch. Also check the continuity between the terminal on the 18-gauge blue/ white wire (w41)
and the bullet terminal on the oil pressure switch brown wire (w90) located above the transaxle.
10. If there is continuity between the 18-gauge purple wire (w40) at the low oil warning light and the 18-gauge purple
wire (w126) at the key switch, replace the low oil warning light. See Warning Light Removal on page 12-5.
11. If the problem is not corrected by performing the previous steps, test the oil pressure switch. See the Briggs &
Stratton Vanguard engine manual (CC P/N 103568101).
TEST PROCEDURE 18 – Fuel Level Sending Unit
See General Warning on page 1-2.
WARNING
• To avoid the possibility of fire or explosion, make sure the fuel tank cap is securely in place while
performing this test procedure.
1. Disconnect battery and spark plug wire(s). See Disconnecting the Battery – Gasoline Vehicles on page 1-4.
2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2k ohms, place the red (+) probe of the multimeter on the center post of the sending unit.
Place the black (–) probe on the ground connection of the sending unit (Figure 11-46, Page 11-34)
4. The following resistance readings (in ohms) should be indicated, depending on the position of the float inside
the fuel tank. The resistance reading will vary according to the exact position of the float. The following table
may be used as a guideline to determine if the fuel level sending unit is operating correctly. Make sure the float
is at the surface of the fuel in the tank.
FLOAT POSITION
Lower position (tank empty)
Center position (tank half full)
Upper position (tank full)
5. If the readings are within the specifications listed in the preceding table, the fuel level sending unit is working
properly. If the readings are incorrect, the fuel level sending unit has failed and must be replaced.
6. If the readings are correct and the fuel gauge does not function correctly, leave the battery disconnected and
check the continuity of the following:
– Orange wire (w05) from the fuel level sending unit to the fuel gauge/hour meter.
– Blue wire (w46) and purple wire (w126) from the fuel gauge/hour meter to the key switch.
– Black ground wires at the fuel level sending unit (w118) and at the fuel gauge/hour meter (w50). See Warning
Light Removal on page 12-5.
7. If the readings are correct according to the position of the float, but the reading on the fuel gauge/hour meter is
incorrect, test the fuel gauge/hour meter. See Test Procedure 19 – Fuel Gauge on page 11-34.
RESISTANCE READING
240 ± 20 ohms
120 ± 30 ohms
60 ± 20 ohms
