Question How does detailed examination of relay coil inrush current protect automotive electrical systems? Answer Excessive inrush current may damage contacts or stress wiring harnesses. Explain When relays engage, the coil draws a transient inrush current significantly higher than steady-state levels. CHEPQ diagnostic equipment captures this transient waveform, allowing technicians to assess coil health and circuit integrity. Abnormal inrush currents may indicate coil short circuits, degraded insulation, or power supply anomalies, which can lead to premature relay failure or wiring overheating. Early detection supports preventive maintenance, avoiding unexpected electrical faults or fire hazards.
