The Takeuchi TL140 is a popular compact track loader known for its durability and performance. However, some operators have reported a situation where there is no power to the coil on the stop solenoid relay. This can prevent the engine from starting, affecting the loader’s ability to perform tasks. In this article, we’ll go over possible causes of the issue and provide a step-by-step guide for troubleshooting and resolving it.
Common Causes of No Power to the Stop Solenoid Coil
Several issues could cause the lack of power to the stop solenoid coil on the Takeuchi TL140. Understanding these causes can help in diagnosing and resolving the problem.
1. Faulty Stop Solenoid Relay
The stop solenoid relay itself might be faulty. The relay is responsible for sending power to the stop solenoid coil, and if it’s malfunctioning, it could be preventing the necessary power from reaching the coil. Testing or replacing the relay could fix the issue.
2. Blown Fuses or Tripped Circuit Breakers
If the relay is receiving power but is still not sending it to the solenoid coil, the issue may be due to a blown fuse or a tripped circuit breaker. A blown fuse in the stop solenoid circuit would prevent the electrical current from flowing correctly.
3. Broken or Loose Wiring
Broken or loose wiring is another common cause of electrical issues in equipment like the TL140. If any wires are disconnected or have poor connections, power may not be able to reach the solenoid coil, preventing the machine from starting.
4. Faulty Stop Solenoid
In some cases, the stop solenoid itself may be faulty. If the solenoid is not functioning properly, even if the relay sends power, the solenoid may not engage, preventing the engine from starting.
5. Ignition or Key Switch Issues
Problems with the ignition switch or the key switch may also prevent power from reaching the stop solenoid relay. If the switch is not sending a signal to the relay, the system won’t be able to power the solenoid coil, and the machine may fail to start.
Troubleshooting Steps
To resolve the issue of no power to the coil on the stop solenoid relay, follow these troubleshooting steps:
A lack of power to the coil on the stop solenoid relay in the Takeuchi TL140 can be caused by various issues, including a faulty relay, blown fuses, broken wiring, a malfunctioning solenoid, or problems with the ignition switch. By systematically following the troubleshooting steps outlined above, you can identify and address the cause of the problem. If the issue persists after these steps, it’s recommended to seek professional assistance for further diagnosis and repair.

Troubleshooting Steps
To resolve the issue of no power to the coil on the stop solenoid relay, follow these troubleshooting steps:
- Step 1: Inspect the Relay
Check the stop solenoid relay for functionality. Use a multimeter to test whether the relay is working correctly. If the relay is faulty, replace it with a new one.
- Step 2: Check Fuses and Circuit Breakers
Inspect the fuses and circuit breakers in the electrical system. Look for any blown fuses or tripped circuit breakers. Replace any blown fuses and reset any tripped breakers to restore power to the circuit.
- Step 3: Examine Wiring Connections
Inspect all wiring connected to the stop solenoid relay and coil. Look for any loose, frayed, or disconnected wires. Ensure all wiring is secure and free of damage.
- Step 4: Test the Stop Solenoid
If the relay and wiring are functioning correctly, test the stop solenoid. Use a multimeter to check for continuity or voltage. If the solenoid is faulty, it may need to be replaced.
- Step 5: Inspect the Ignition Switch
If none of the above steps resolve the issue, check the ignition or key switch. If the switch is malfunctioning, it might not be sending the proper signal to the relay. Replace the switch if necessary.
