Wiring Diagram

The following is a wiring diagram for the 6-volt electrical system of the Farmall Cub:

Description of the Wiring Diagram

The wiring diagram is divided into two sections: the main circuit and the ignition circuit. The main circuit provides power to the lights, horn, and starter. The ignition circuit provides power to the spark plugs.

Main Circuit

The main circuit is powered by the battery. The battery is connected to the starter solenoid, which is in turn connected to the starter motor. The starter motor engages the flywheel, which starts the engine. The engine then provides power to the alternator, which charges the battery. The main circuit also provides power to the lights, horn, and starter switch. The lights are connected to the battery through the fuse block. The horn is connected to the battery through the ignition switch. The starter switch is connected to the battery through the starter solenoid.

Ignition Circuit

The ignition circuit is powered by the battery. The battery is connected to the ignition switch, which is in turn connected to the coil. The coil generates a high voltage spark that is sent to the spark plugs. The spark plugs ignite the fuel in the cylinders, which causes the engine to run. The ignition circuit also provides power to the distributor. The distributor distributes the spark to the spark plugs in the correct order.

Troubleshooting

If the Farmall Cub is not starting, there are a few things that you can check. First, check the battery to make sure that it is charged. If the battery is not charged, you will need to charge it or replace it. Next, check the fuses to make sure that they are not blown. If a fuse is blown, you will need to replace it. Finally, check the wiring to make sure that it is not damaged. If the wiring is damaged, you will need to repair it.

Conclusion

The Farmall Cub was a popular tractor that was produced for many years. The 6-volt electrical system was simple and reliable. If you have a Farmall Cub and are having trouble with the electrical system, this article should help you troubleshoot the problem.
