- Taiyo generators originally equipped with DST-100-2FA4 regulator — confirm alternator head and wiring
Product Overview
A failed AVR can cause high, low or unstable voltage even when the engine runs normally. Before replacement, check excitation wiring, brush condition where applicable and the generator’s electrical specifications.
AVRs can look similar while using different sensing voltages and pinouts. Match the original regulator label, plug arrangement and adjustment range.
