Abstract
A Fuel System for an engine includes an actuator for controlling the output of a pump and a pair of d.c. supply lines the voltage across which is determined by a voltage regulator. A series circuit including a resistor, a relay coil and a transistor is connected across the supply lines and first means is provided for turning transistor off if the current flow through the actuator exceeds a predetermined value. Second means including a resistor is provided to maintain transistor de-energised when it has been turned off to prevent further operation of the actuator. In addition switch means is provided to short circuit the resistor if the potential between the supply lines falls below a second predetermined value.
