Electrical Circuit Malfunction and Diagnosis of Tractors
Electrical circuits are an essential part of tractor running and functions. Proper function of the circuit elements and the lack of circuit malfunctions are the basis of the trouble-free operation of the tractor. This article explores the common electrical circuit malfunctions of tractors and suggests ways to diagnose and prevent them.
Common electrical problems arise from the tractors battery and alternator. The battery is the power source that provides power to run the tractor, while the alternator reverses the current and recharges the battery while the tractor is running. Two common problems related to these two components are loose or corroded battery cables and a weak alternator. Battery cables are often loose due to vibration, which can result in over-heating and even failure of the system. Corrosion on the cables can lead to a voltage drop and can prevent the battery from charging properly. To diagnose the problem, a technician should check for loose or corroded connections, as well as excessive amp draws. A faulty alternator is a result of a worn-out or broken bearing, or a worn pulley or belt. To diagnose the problem, the technician should check the pulley, belt and bearing for any signs of wear or failure.
The ignition system of the tractor is also prone to malfunctions. Typically, the primary symptoms of an ignition system problem are difficult starting, engine stalling and loss of power. The three main components of the ignition system are the spark plugs, spark plug wires and distributor. A weak spark plug, loose wire connection or a faulty distributor can cause difficulties with the ignition system. To diagnose a possible problem, the technician should check for signs of wear and tear on the spark plugs and wires, and for any loose connections.
To diagnose a possible electrical problem, a technician should be aware of the most common causes of the issue. Listed below are the three most common electrical circuit malfunctions of tractors:
1. Loose or corroded battery cables
2. Weak alternator
3. Weak spark plug, loose wire connection or faulty distributor
When an electrical problem is suspected, the technician should use a combination of visual inspections, electrical test equipment such as voltmeters and test benches and computer-aided diagnostics to determine the root cause.
Finally, to prevent electrical malfunctions, the tractor owner should perform regular maintenance on the electrical system. This includes checking the battery cables and connectors for corrosion, inspecting the spark plug and wires for signs of wear, replacing the battery and spark plugs when necessary, and having the alternator serviced periodically. Regular maintenance of the tractors electrical system will help to keep its circuits running at their peak performance and prevent future malfunctions.
