A rectifier converts alternating current (AC) produced by the machine's charging system into the direct current (DC) that the battery and electrical components require. Without a properly functioning rectifier, the charging circuit cannot maintain the battery, and unregulated voltage can damage connected electrical components over time. When this component fails, operators typically notice a battery that won't hold a charge or erratic electrical behavior — replacing it promptly restores normal charging and protects the rest of the system.
