Battery

The battery is the heart of the electrical system on the Honda Rebel 250. It supplies power to all the electrical components on the motorcycle. The wiring diagram shows the battery connected directly to the main fuse and the starter solenoid.

In the event of a dead battery, check the connections at the battery and make sure it is fully charged. A bad battery can cause the entire electrical system to fail.

Main Fuse

The main fuse is a protective device that disconnects the battery in case of electrical overload. The wiring diagram shows the main fuse connected directly to the battery and the ignition switch. If the main fuse is blown, the entire electrical system will be dead.

To replace the main fuse, locate the fuse box under the seat and remove the old fuse. Install a new fuse with the correct amperage rating to avoid electrical damage.

Ignition Switch

The ignition switch controls the flow of power to the ignition system, allowing the engine to start and run. The wiring diagram shows the ignition switch connected to the main fuse, starter solenoid, and ignition system.

If the ignition switch fails, the motorcycle will not start. Check the connections at the switch and make sure it is securely mounted to the handlebars.

Ignition System

The ignition system provides spark to the engine for starting and running. The wiring diagram shows the ignition system connected to the battery, ignition switch, spark plug, and engine ground.

If the engine fails to start or runs poorly, check the connections at the ignition coil and spark plug. Make sure the spark plug is clean and properly gapped.

Charging System

The charging system recharges the battery while the engine is running. The wiring diagram shows the charging system connected to the alternator, voltage regulator, and battery.

If the battery fails to charge, check the connections at the alternator and regulator. Make sure the alternator is properly grounded and the regulator is functioning correctly.

Lighting System

The lighting system provides lighting for the motorcycle. The wiring diagram shows the lighting system connected to the battery, headlight, turn signals, and brake light.

If the lights fail to work, check the connections at the headlight and light switches. Make sure the bulbs are not burned out and the fuses are not blown.

Accessory Circuit

The accessory circuit provides power for additional accessories such as a GPS or heated grips. The wiring diagram shows the accessory circuit connected to the battery and accessory fuse.

If the accessories fail to work, check the connections at the accessory fuse and make sure the accessory switch is in the on position.

Grounds

The grounds provide connection points for the negative side of the electrical system. The wiring diagram shows several grounding points throughout the motorcycle.

If the electrical system fails to work, check the grounding connections and make sure they are clean and have a good connection.
