Signal System

SIGNAL SYSTEM

B. Signal system tests and checks The battery provides power for operation of the horn, brakelight, indicator lights and flasher light. If none of the above operates, always check battery voltage before proceeding further. Low battery voltage indicates either a faulty battery, low battery water, or a defective charging system. See  "CHARGING SYSTEM" for checks of battery and charging system. Also check fuse condition. Replace any "open" fuses. There are individual fuses for various circuits (see complete Circuit Diagram).

1.    Horn does not work:

a.   Check for 12V on brown wire to horn.

b.  Check for good grounding of horn {pink wire) when horn button is pressed.

2.    Brake light does not work:

a.   Check bulb.

b.  Check for 12V on yellow wire to brake light.

c.   Check for 12V on brown wire to each brake light switch (front brake and rear brake switches).

3.    Flasher lights(s) do not work:

a.   Check bulb.

b.   Right circuit:

1)  Check for 12V on dark green wire to light.

2)  Check for ground on black wire to light assembly.

c.   Left circuit:

1)  Check for 12V on dark brown wire to light.

2)  Check for ground on black wire to light assembly.

d.   Right and left circuits do not work:

1)  Check for 12V on brown/white wire to flasher switch on left handlebar.

2)  Check for 12V on brown wire to flasher relay.

3)   Replace flasher relay.

4)   Replace flasher switch.

e.   Check flasher self-cancelling system. (Refer to flasher self-cancelling system.)

4. Neutral light does not work:

a.   Check bulb.

b.  Check for 12V on sky blue wire to neutral switch.

c.   Replace neutral switch.

6. Oil level warning light does not work:

a.   Connect oil level switch (black/red wire) to ground. If light comes on, check for proper oil level.

b.   If oil level is correct, replace oil level switch.

C. Self-cancelling flasher system

1.    Description:

The self-cancelling flasher system turns off the turn signal after a period of time or distance involved in turning or changing lanes. Generally, the signal will cancel after either 10 seconds, or 150 meters (490 feet), whichever is greater. At very low speed, the function is determined by distance; at high speed, especially when changing speeds the cancelling determination is a combination of both times and distance.

2.    Operation:

The handlebar switch has three positions: L (left), OFF, and R (right). The switch lever will return to the "OFF" position after being pushed to L or R, but the signal will function. By pushing the lever in, the signal may be cancelled manually.

3.    Inspection

If the flasher self-cancelling system should become inoperative, proceed as follows:

a. Pull off the 6-pin connector from the flasher cancelling unit, and operate the handlebar switch, if the signal operates normally in L, R, and OFF, the following are in good condition.

1)  Flasher unit

2)  Bulb

3)   Lighting circuit

4)  Handlebar switch light circuit

If (1) through (4) are in good condition, the following may be faulty:

1)   Flasher cancelling unit.

2)  Handlebar switch rear circuit.

3)  Speedometer sensor circuit.

b.   Pull off the 6-pin connector from the flasher cancelling unit, and connect a tester (ohms x 100 range) across the white/green and the black lead wires on the wire harness side. Turn the speedometer shaft. If the tester needle swing back and forth between 0 and co, the speedometer sensor circuit is in good condition. If not, the sensor to wire harness may be inoperative.

c.   Pull the 6-pin connector from the flasher cancelling unit. Check if there is continuity between the yellow/red lead wire on the wire harness side and the chassis.

Flasher switch OFF: co Flasher switch L or R: 0 ohms

If the tester needle does not swing as indicated above, check the handlebar switch circuit and wire harness.

d.   If no defect is found with the above three check-ups and the flasher cancelling system is still inoperative, replace the flasher cancelling unit.

e.   If the signal flashes only when the handlebar switch lever is turned to L or R and it turns off immediately when the handlebar switch lever returns to center, replace the flasher cancelling unit.
