Tractor Wiring
There is an art to wiring a tractor, and this art can be applied to any other type of farm machinery as well. Although all tractors have wiring to do with feeding power into the battery, there are many variations to the way that different models and brands have their wiring systems set up. While most manufacturers try to keep their product easy to work with by offering step by step instructions that are printed on the box, not every tractor will follow these same guidelines. The best advice for a tractor owner is to consult a professional repairman or dealership that sells new and used tractors to give you suggestions on what kind of wiring to put on your machine.
Many newer models of electric and gas tractors have a sealed casing that makes it easy to install the wiring; however, older model tractors may still require some manual labor if you are going to put the wiring in yourself. Some general guidelines for tractor wiring are to put the main cable in the back, in the rear, and tie the neutral wire to the battery. This is also the time to put the return plug if you are hooking the power cord from the battery directly back to the tractor. This can prevent damage to the power box if you accidentally pull the cord while the tractor is powered. Remember, electric and gas tractors all have a closed loop system that consists of multiple wires that are heated so they can conduct electricity. Once you start to connect anything to these wires, you need to reverse the process so you can then feed the wires back into the tractor.
You can help yourself along by starting off with your vehicle's electrical system, which includes the starter and the igniter. If you find that the starter is not turning on, it could be because the ignition wiring has not been wired to the tractor. In this case, you need to take apart the starter so you can feed the wiring back through the starter. One mistake most people make is when they start the vehicle up, they hook their starting circuit to the battery instead of the fuse. This is a big mistake because you want to first feed the wiring back to the engine.
