PURPOSE: An electrical circuit diagram is provided to prevent a voltage drop by reducing the wiring length between the battery and fuel motor. CONSTITUTION: An electrical circuit diagram comprises an ECU relay(20) which operates by the control of an ECU when a power is applied to an ignition terminal; a low flow rate fuel pump relay(10) serially connected to the ECU relay; a fuel pump register(30) and a high flow rate fuel pump relay(40) which are connected in parallel with each other so as to supply a power from a battery to a fuel pump motor when a power is applied to the low flow rate fuel pump relay; and a voltage drop display for comparing the voltage of the battery and the voltage supplied from a motor, and alarming the occurrence of voltage drop.
