A method for testing electrical loads in a vehicle electrical system is provided, in which the loads, which are fed by a vehicle battery, are selectively switched on and off. The load-specific current consumption in the switched-on state is determined and assessed in each case. The battery voltage is measured immediately before and shortly after the switching-off of a previously switched-on load in order to determine the load-specific current consumption value from the load-specific battery voltage difference. The internal resistance of the battery serves indirectly as the measuring resistance, which is determined by loading the battery with a known load on a trial basis.
