A common issue with the TL140 skid steer is when you hear a clicking sound after pressing the start button, but the engine doesn't turn over. This typically indicates a problem in the electrical or starting system. Here are the key steps to troubleshoot this issue:
1. Low Battery Voltage
If the battery voltage is too low, the starting current won't be enough to start the engine. First, check the battery voltage. If it's below 12 volts, try charging the battery or replacing it.
2. Starter Motor Problem
If the battery voltage is fine, but you still only hear a click when you press the start button, the issue might be with the starter motor. The starter motor's gear may be stuck, or the internal solenoid might be faulty. Remove the starter motor and inspect its internal components for any issues.
3. Electrical Connection Check
Loose or corroded electrical connections can also cause starting problems. Check the battery terminals, starter motor wiring, and ground connections to ensure they are clean and secure.
4. Safety Switch Issues
The TL140, like many machines, has several safety switches that can prevent the engine from starting under certain conditions. For example, if the seat sensor or engine protection switch is not properly engaged, the system may perceive the machine as unsafe and prevent starting.
5. Relay Failure
Relays are responsible for transmitting the start signal. If a relay fails, the current can't reach the starter motor, which results in a no-start condition. Check whether the relays are working correctly.
6. Solenoid and Starter Coil Issues
The solenoid and starter coil inside the starter motor may also be faulty. These types of failures typically require professional repair.
Conclusion
When the TL140 makes a clicking sound but won't start, begin by checking the battery voltage, starter motor, and electrical connections. If these components check out, move on to inspecting the safety switches and relays. With systematic troubleshooting, you can identify and resolve the issue.
