Common faults and symptoms
Common faults for the EGT-120 often present with tangible operational changes such as abnormal engine sounds, rough idling, or loss of power. If the unit fails to start, inspect the ignition system, including spark plugs, ignition coils, and wiring for signs of wear or corrosion. For engines that start but stall under load, examine the fuel system for restricted fuel flow, dirty filters, or air leaks in the intake manifold. Overheating can manifest as reduced performance and automatic shutdowns; check coolant levels, radiator cleanliness, and thermostat function, ensuring there are no obstructions in the cooling path. Electrical faults may show up as intermittent operation or complete non-responsiveness; inspect main fuses, wiring harness continuity, and ground connections for looseness or corrosion. Finally, mechanical issues like excessive vibration or knocking often point to worn bearings, unbalanced accessories, or loose mounting hardware that requires attention. Each symptom should be cross-validated with multiple checks to prevent misdiagnosis.
In addition to engine-specific symptoms, control system indicators such as display warnings or audible alarms provide critical clues. A blinking or solid fault LED usually corresponds to a saved fault code in the control unit, which aids in rapid identification of the subsystem involved. If the machine experiences reduced imaging of sensors or erratic feedback to the control panel, sensor calibration or wiring faults must be inspected. For hydraulic or pneumatic subsystems, look for leaks, pressure inconsistencies, or muffled hydraulic noises that indicate compromised seals or worn components. Recording the exact symptom, time of occurrence, engine load, and ambient conditions helps compile a history that can reveal intermittent faults that are otherwise elusive. Thorough documentation supports accurate diagnosis and efficient repairs.
Diagnostic flowcharts
Diagnostic flow for the EGT-120 begins with a safe shutdown and a visual inspection, followed by a stepwise electrical check to verify basic power and grounding. Start by confirming the battery voltage and ensuring secure terminal connections, then proceed to inspect fuses and protective relays for signs of blown circuits or overheating. If electrical power is solid, move to ignition and starting systems, testing spark quality, coil integrity, and fuel delivery prerequisites. When the engine runs but performance is compromised, isolate the fuel, air, and exhaust subsystems to determine where flow is restricted or contaminated. Each step should be performed with the engine in the recommended test mode and with proper PPE, maintaining a log of measurements and observed results for traceability. The flowchart logic guides you toward the subsystem most likely responsible, preventing unnecessary disassembly of components that are functioning correctly. This systematic approach reduces diagnostic time and increases repair accuracy.
For cooling and lubrication concerns, the diagnostic path includes checking coolant levels, radiator passage, and thermostat operation, followed by the inspection of oil quality, level, and filter conditions. If overheating persists despite adequate coolant, consider airflow obstructions such as debris in the shroud or fan blade damage. When load-related faults are suspected, verify governor performance, fuel pump pressure, and sensor feedback under load conditions. In every case, compare findings with manufacturer specifications and diagnostic thresholds, adjusting test procedures to match the exact model revision of the EGT-120. Document deviations from standard values, as these can indicate component wear or developing faults that require proactive maintenance rather than immediate replacement.
Finally, a structured troubleshooting path includes reverting to known-good configurations, performing a controlled reset of programmable parameters, and rechecking system responses after reassembly. If fault codes are stored in the control unit, refer to the code interpretation guide to map each code to a probable subsystem. Always validate repairs by running the unit through a full operational cycle, checking for return of normal parameters such as temperature, pressure, and electrical readings to specified ranges. By adhering to the diagnostic flowcharts, technicians can produce repeatable, reliable results and maintain a high standard of service quality for the EGT-120.
Error codes and interpretations
Error codes provide a concise summary of detected faults from the control system, aiding rapid decision-making during diagnostics.
