Product Details

Obsolete, no replacement, none in stock


The circuit breaker's function is to cut off electrical power if wiring is overloaded with current, or if their is a short circuit. Turn the circuit breaker off before starting the engine and before you shut the engine down; this is due to the fact that the generator will try to produce electricity until the engine comes to a complete stop. This could damage the AVR (Automatic Voltage Regulator) as it attempts to produce power even when the engine is turning at low RPM’s during shut-down.
