Voltage Regulator Rectifier
The regulator is designed to limit stator output to approximately 14.4V; a failure in the internal Zener diode or control circuit allows the full, unregulated stator voltage to reach the battery. This excessive voltage causes the battery's lead-acid chemistry to reach its gassing point, resulting in the 'boiling' effect and thermal expansion. The flickering headlights are caused by high-amplitude AC ripple current bypassing the failed rectifier diodes, which interferes with the DC electrical system's stability.
