Case 420 Shutdown and Won't Restart Issue - MikePhua - 07-05-2025 The Case 420 experienced a starting issue where the equipment could not restart after shutting down, with no electrical response. Problem Description The user reported that after finishing work, the Case 420 was turned off, but it failed to restart. Upon initial inspection, the user thought the issue might be due to a low battery or a fault in the starting circuit. Diagnosis and Solution Further diagnosis revealed that the battery was fully charged, and the electrical lines were intact. The root cause of the issue was a faulty starter relay. The relay was unable to complete the circuit, preventing the engine from receiving the necessary start-up current. After replacing the starter relay, the equipment started working normally again. Conclusion and Recommendations This issue emphasizes the need for regular checks on the starting system, particularly the starter relay, battery, and wiring. Routine maintenance of these components can help prevent startup failures due to minor faults. |
