The starting circuit is one of the core electrical components of the TL130, responsible for starting the engine and providing the necessary power. The wiring diagram clearly shows the connections between the battery, starter motor, and relays. When troubleshooting, users should first check the battery charge, the condition of the starter motor, and ensure that the wiring connections are intact.

1. Lighting System
   

The lighting system includes front and rear headlights, work lights, and turn signals to ensure visibility during operation. The wiring diagram outlines the connections of the lighting system, which is useful for diagnosing light-related issues such as burnt-out bulbs or open circuits.

1. Hydraulic Control System
   

The hydraulic control system's electrical components include solenoid valves that control the hydraulic pump and valve functions. The wiring diagram displays the electrical connections between solenoid valves, hydraulic pumps, and control levers. By inspecting the solenoid valve and switch connections, users can ensure that the hydraulic system is functioning as it should.

1. Sensors and Control Modules
   

The TL130 is equipped with various sensors that monitor engine temperature, oil pressure, and hydraulic pressure. The wiring diagram shows the connections between these sensors and the control modules, which helps in locating issues such as sensor failures or abnormal signal readings.
Troubleshooting Common Wiring Issues

1. Low or Faulty Battery Voltage
   

If the TL130 fails to start, one of the first things to check is the battery voltage. The wiring diagram shows the connection between the battery and the starting system. By inspecting the battery voltage and checking the connections, users can determine if the issue lies with the battery or the wiring.

1. Relay and Fuse Issues
   

Relay and fuse failures are common electrical problems. The wiring diagram indicates the protection method for each electrical component, making it easier to check whether a relay is malfunctioning or a fuse has blown. Ensuring that the relays and fuses are intact can eliminate some of the most common electrical faults.

1. Solenoid Valve Failures
   

The solenoid valves in the hydraulic system control the operation of the hydraulic pump. If the solenoid valve fails, the hydraulic system may not operate correctly. Checking the solenoid valve power supply and control signals through the wiring diagram can help ensure the electrical connections are intact and that the valve is functioning properly.

1. Sensor and Control Module Failures
   

If sensors or control modules malfunction, the equipment may not function correctly. For example, a faulty engine temperature sensor could cause false overheating alerts. Using the wiring diagram, users can trace the sensor wiring and control module connections to pinpoint faults and replace or repair the defective components.
Maintaining and Updating the Wiring Diagram

1. Regularly Inspect the Wiring Diagram
   

As the machine is used and ages, the components and wiring in the electrical system may change or degrade. Regularly inspecting and updating the wiring diagram ensures it remains accurate, making it easier to perform maintenance or troubleshooting. This can save time and reduce errors when diagnosing electrical issues.

1. Backup the Wiring Diagram
   

It is crucial to keep a backup of the wiring diagram for each machine. This ensures that in case of an emergency, you can quickly refer to the diagram for troubleshooting. The diagram should be stored in a safe place to prevent loss or damage, ensuring quick access when needed.

1. Seek Professional Support
   

If the wiring diagram doesn’t help resolve complex electrical issues, it is advisable to contact professional technical support or an authorized service center. Takeuchi’s authorized dealers can provide detailed wiring diagrams and offer expert assistance to quickly identify and fix problems.
