Honda NTV650 Revere - Ignition Troubleshooting
Spark unit
Green/White | Ground | It connects to the ground when it is OK to run the engine. Goes to the clutch switch, the side stand switch and the neutral switch diode. |
---|---|---|
Yellow/Blue | Goes to the rear ignition coil. Gets the +12V battery voltage when the engine stop switch is on the RUN position and the ignition switch is ON. | |
Black/White | +12V | It gets the +12V through fuse #6 when the engine stop switch is on the RUN position and the ignition switch is ON. Goes to the ignition coils and to the engine stop switch. |
Blue/Yellow | Goes to the front ignition coil. Gets the +12V battery voltage when the engine stop switch is on the RUN position and the ignition switch is ON. | |
Green | Ground | Always connected to the ground. |
Light green/Red | Ground | It connects to the ground when the gear is in neutral position. Goes to the neutral switch. |
Starter relay switch
Green/Red | Ground | It gets the ground when is it OK to start the engine. Goes to the clutch switch, to the side stand switch and to the neutral switch diode. |
---|---|---|
Yellow/Red | +12V | It gets the +12V through fuse #6 when the start button is pressed. Goes to the starter switch. |
Fuel pump relay and fuel pump
Blue/Black | +12V | It gets the +12V when the relay is switched-on (the engine is running). Goes from the fuel cut relay to the fuel pump. |
---|---|---|
Black | +12V | It gets the +12V when the ignition switch is ON. It goes to the fuse #6. |
Blue/Yellow | It gets the signal from the ignition coils to switch the relay ON. It goes to the spark unit. |
Ignition coils and pulse generator
Measure the resistance of the primary and secondary ignition coils, then the resistance of the pulse generator coils. Reference values are for 20°C/68°F.
Primary coil resistance
- Blue/Yellow - Black/White (rear): 2.2 - 2.6 Ω (ohm)
- Yellow/Blue - Black/White (front): 2.2 - 2.6 Ω (ohm)
Secondary coil resistance
- Between spark plug caps: 30 - 36 kΩ (kohm)
- Between terminals (spark plug wires removed): 20 - 25 kΩ (kohm)
Pulse generator resistance
- White/Yellow - Yellow (front): 450 - 550 Ω (ohm)
- White/Blue - Blue (rear): 450 - 550 Ω (ohm)
