The method of instantly making use of battery voltage to the sector winding of an alternator to power most output is termed “full fielding.” This bypasses the voltage regulator, compelling the alternator to supply its highest doable voltage and present. An instance is when diagnosing an alternator failure, this system can shortly reveal if the alternator itself is able to producing energy, isolating it from regulator points.
Using this methodology serves an important diagnostic operate, significantly in situations the place charging system malfunctions are suspected. The observe permits technicians to shortly decide the alternator’s potential output functionality. Traditionally, this was a typical troubleshooting step on older autos with easier charging programs; nonetheless, warning should be exercised on fashionable autos with subtle digital controls, as extreme voltage can harm delicate elements.
