The invention provides a high-efficiency energy-dissipation board turning circuit for a fault indicator. The circuit is composed of a diode D9, a diode D7, a diode D12, a triode Q1, a triode Q2, a capacitor C24, a capacitor C37, a capacitor C38, a capacitor C24, a capacitor C23, a resistor R23, a resistor R24, a resistor R28, a resistor R27, a resistor R17, a resistor R26, a resistor R29 and a board turning coil JP3. Therefore, the battery service life of the fault indicator can be protected. When the battery capacity is reduced, the reliable board turning energy still can be provided, thereby improving reliability of the fault indictor product.
