CAT 252 Inoperable Issue and Solution - MikePhua - 07-05-2025
A user encountered an issue with the CAT 252, where the equipment failed to operate. This issue prevented the equipment from starting, and there was no response when attempting to start the machine.
Problem Description
When attempting to start the vehicle, there was no response at all. After several attempts, the user discovered that not only was the machine failing to start, but the basic electrical system wasn't functioning properly either. The battery voltage was confirmed to be normal, and there were no visible signs of loose or corroded cables, suggesting that the issue might be related to some components of the electrical system.
Diagnosis and Solution
After diagnosis, some users suggested checking the vehicle's main contact switch and fuses. It was discovered that the main contact switch of the vehicle was faulty, preventing the current from properly reaching key components. After replacing the contact switch, the equipment was able to operate normally again.
Conclusion and Recommendations
Once the equipment was operational again, it was recommended that the user regularly check the electrical system components, especially the connections and switches, to avoid failures that could prevent the machine from starting. Additionally, maintaining the battery’s charge is crucial.
