XRV750L to N 1990 to 1992 models

Check - warning light circuit

1 XRV750-L to N (1990 to 1992) models are fitted with a fuel warning light circuit checker (see illustration 15.2b). When the ignition is switched ON, both low fuel warning lights (one red. one orange) should come on for a few seconds, then extinguish. If they do not. first check the fuses, then check the bulbs (see Chapter 9). If they are good, check the fuel sensor and its circuit (see below).

2 If all is good so far, disconnect the wiring connector from the circuit checker, located below the instrument cluster on the right-hand side. With the ignition switch ON. check for battery voltage between the black (+) and green/white (-) wire terminals on the connector. There should be battery voltage. If not, check the wiring and connectors for faults, referring to the Wiring Diagrams at the beginning of the Chapter. If there is voltage, the checker is faulty and must be replaced with a new one.

Check - fuel sensor circuit

3 The circuit consists of the fuel level sensor mounted in the fuel tank and the low fuel warning light mounted in the instrument panel. If the system malfunctions first check that the bulb and fuses are good (see Chapter 9).

4 Remove the left-hand fairing side panel (see Chapter 8). Disconnect the fuel level sensor wiring connector, located below the tank on the left-hand side. Also disconnect the wiring connector from the circuit checker, located below the instrument cluster. Using an insulated jumper wire, short between the orange/white and green wire terminals on the loom side of the sensor wiring connector. Turn the ignition switch ON. If the orange warning light comes on. check the orange/white and green wires between the connector and the sensor itself in the tank for loose or broken connections. If the wiring is good, replace the sensor with a new one. If the orange warning light does not come on, check wiring between the connector and the instrument cluster for loose or broken connections.

5 Now short between the grey/black and green wire terminals on the loom side of the sensor wiring connector. Turn the ignition switch ON. If the red warning light comes on, check the grey/black and green wires between the connector and the sensor itself In the tank for loose or broken connections. If the wiring is good, replace the sensor with a new one. If the orange warning light does not come on, check wiring between the connector and the instrument cluster for loose or broken connections.

Replacement

6 See Chapter 9 for replacement of the warning light bulb.

7 To replace either sensor, remove the fuel tank and drain it (see Section 2). Disconnect the wiring connectors from the sensor.

8 Unscrew the sensor and draw it out of the tank. Discard the O-ring. Fit a new O-ring onto the sensor. Apply a smear of suitable sealant to the upper portion of the sensor threads, then screw it into the tank and tighten it to the torque setting specified at the beginning of the Chapter.

9 Install the tank (see Section 2). and check carefully for leaks before using the bike.
