| Black | Ground | 10 | Tractor Frame |
Battery Positive
The battery positive wire is red and is used to supply power to the starter motor and solenoid. The wire gauge is 10, and the location is on the starter motor and solenoid.
The starter motor is responsible for turning the engine over to start the tractor. The solenoid is an electromechanical switch that engages and disengages the starter motor.
Ignition Switch Positive
The ignition switch positive wire is red and blue and is used to supply power to the coil, alternator, and regulator. The wire gauge is 14, and the location is on the coil, alternator, and regulator.
The coil is responsible for generating the high voltage required to ignite the fuel in the engine. The alternator and regulator are responsible for charging the battery and providing power to the electrical system.
Accessory
The accessory wire is yellow and white and is used to supply power to switches, lights, and gauges. The wire gauge is 14, and the location is on switches, lights, and gauges.
Switches are used to control various functions of the tractor, such as lights, wipers, and fans. Lights are used to illuminate the tractor, making it visible in low light conditions. Gauges are used to monitor various parameters of the tractor, such as fuel level and engine temperature.
Field Circuit
The field circuit wire is green and is used to control the alternator’s output voltage. The wire gauge is 16, and the location is on the alternator and regulator.
The alternator is responsible for recharging the battery and providing power to the electrical system. The regulator is used to control the alternator’s output voltage, ensuring that the battery is not overcharged or undercharged.
Start Circuit
The start circuit wire is green with an orange stripe and is used to supply power to the starter motor and solenoid during starting. The wire gauge is 16, and the location is on the starter motor and solenoid.
The start circuit is activated when the ignition key is turned to the start position, sending power to the starter motor and solenoid to engage the engine’s starting process.
Negative Ground
The negative ground wire is black with an orange stripe and is used to ground the battery. The wire gauge is 10, and the location is on the battery.
The battery’s negative terminal is connected to the tractor frame, providing a ground connection for the electrical system.
Ground
The ground wire is black and is used to connect the electrical components to the tractor frame. The wire gauge is 10, and the location is on the tractor frame.
The ground wire provides a path for electrical current to flow back to the battery, completing the electrical circuit.
