International Harvester introduced the 1486 tractor in 1974 to replace the popular 1466 model. The 1486 was a part of the IH 86-series tractors, which included the 786, 886, and 986 models. The 1486 featured an 836 ci six-cylinder diesel engine and was capable of producing 161 horsepower. This model was known for its reliability, power, and versatility. To keep the tractor running smoothly, it is essential to have access to the wiring diagram.
What is the Wiring Diagram?
The wiring diagram shows the electrical wiring and connections of the tractor. It includes information on the color-coded wires and the routing of the cables. The wiring diagram is essential for troubleshooting electrical problems and for making repairs or modifications.
Why is the Wiring Diagram Important?
The wiring diagram is important because it helps to ensure that the electrical system of the tractor is installed correctly. It can also help to identify and fix electrical problems quickly. Without the wiring diagram, it would be challenging to determine which wire goes where and how the system should be connected.
Where Can I Find the Wiring Diagram?
The wiring diagram can be found in the tractor’s operator’s manual or service manual. These manuals can be obtained from International Harvester dealerships or online.
What If I Don’t Have Access to the Manual?
If you don’t have access to the manual, you can try contacting International Harvester or a local tractor repair shop. They may be able to provide you with a copy of the wiring diagram.
Understanding the Wiring Diagram
The wiring diagram can look complicated, but it can be broken down into sections to make it easier to understand. Each section may show the wiring for a specific component or system within the tractor.
Basic Components in the Wiring Diagram
The basic components shown in the wiring diagram include the battery, starter, alternator, ignition, lights, and gauges. Each component will have its own symbols and wires that are color-coded to make it easier to trace. It is essential to read the key and legend provided in the diagram to make sense of the symbols used.

Reading the Wiring Diagram
When reading the wiring diagram, it is essential to follow the path of the wires and to understand how they are connected. Each wire will have a specific function and must be connected correctly to ensure the electrical system’s proper operation.
When troubleshooting electrical problems, it is helpful to have a multimeter or test light to check for continuity or voltage. Following the wiring diagram’s path can help to identify where the problem is and how to fix it.
Conclusion
The 1486 International Wiring Diagram is an essential tool for maintaining and repairing your tractor’s electrical system.
