Note: Before troubleshooting, remove the following part(-s):
- 1) battery cover
- 2) rider's seat
- 3) fuel tank
- 4) steering head side covers
- 5) left side cover
- Troubleshoot with the following special tool(-s).
- Pocket tester: 90890-03112
1. Main and ignition fuses
Check the main and ignition fuses for continuity. Refer to "Checking the fuses".
Are the main and ignition fuses OK?
NO: Replace the fuse(-s).
YES:
2. Battery
Check the condition of the battery. Refer to "Checking and charging the battery".
Open-circuit voltage: 12.8 V or more at 20°C
Is the battery OK?
NO: Clean the battery terminals. Recharge or replace the battery.
YES:
3. Starter motor
Connect the battery positive terminal (1) and starter motor lead (2) with a jumper lead (3).
Warning!
- A wire that is used as a jumper lead must have at least the same capacity of the battery lead, otherwise the jumper lead may burn.
- This check is likely to produce sparks, therefore make sure that no flammable gas or fluid is in the vicinity.
Does the starter motor turn?
NO: Repair or replace the starter motor.
YES:
4. Starting circuit cutoff relay
Disconnect the relay unit from the coupler.
Connect the pocket tester (Ω x 1) and battery (12V) to the relay unit terminals as shown.
- Battery positive terminal → red/black (1)
- Battery negative terminal → black/yellow (2)
- Tester positive probe → blue (3)
- Tester negative probe → black (4)
Does the starting circuit cutoff relay have continuity between black and blue/white?
NO: Replace the relay unit.
YES:
5. Starting circuit cutoff relay (Diode)
Disconnect the starting circuit cutoff relay from the coupler.
Connect the pocket tester (Ω x 1) to the starting circuit cutoff relay terminals as shown.
Measure the starting circuit cutoff relay for continuity as follows.
- Tester positive probe → sky blue (1): Continuity
- Tester negative probe → black/yellow (2): Continuity
- Tester positive probe black/yellow (2): No continuity
- Tester negative probe sky blue (1): No continuity
Note: When you switch the "-" and "+" leads of the digital pocket tester the readings in the above chart will be reversed.
Are the tester readings correct?
NO: Replace the relay unit.
YES:
6. Starter relay
Disconnect the starter relay from the coupler.
Connect the pocket tester (Ω x 1) and battery (12 V) to the starter relay coupler as shown.
- Battery positive terminal → red/white (1)
- Battery negative terminal → blue (2)
- Tester positive probe → red (3)
- Tester negative probe → black (4)
Does the starter relay have continuity between red and black?
NO: Replace the starter relay.
YES:
7. Main switch
Check the main switch for continuity. Refer to "Checking the switches".
Is the main switch OK?
NO: Replace the main switch.
YES:
8. Engine stop switch
Check the engine stop switch for continuity. Refer to "Checking the switches".
Is the engine stop switch OK?
NO: Replace the right handlebar switch.
YES:
9. Neutral switch
Check the neutral switch for continuity. Refer to "Checking the switches".
Is the neutral switch OK?
NO: Replace the neutral switch.
YES:
10. Sidestand switch
Check the sidestand switch for continuity. Refer to "Checking the switches".
Is the sidestand switch OK?
NO: Replace the sidestand switch.
YES:
11. Clutch switch
Check the clutch switch for continuity. Refer to "Checking the switches".
Is the clutch switch OK?
NO: Replace the clutch switch.
YES:
12. Start switch
Check the start switch for continuity. Refer to "Checking the switches".
Is the start switch OK?
NO: Replace the right handlebar switch.
YES:
13. Diode
Check the diode for continuity. Refer to "Ignition system".
Is the diode OK?
NO: Replace the diode.
YES:
14. Wiring
Check the entire starting system's wiring. Refer to "Circuit diagram".
Is the starting system's wiring properly connected and without defects?
NO: Properly connect or repair the starting system's wiring.
YES: The starting system circuit is OK.
