The invention relates to an on-board motor vehicle electrical system (1) comprising a first voltage supply system (2a) and comprising a second voltage supply system (2b). The first voltage supply system (2a) has a first voltage source with a relatively low voltage, and the second voltage supply system (2b) has a second voltage source with a relatively high voltage. The first voltage supply system (2a) and the second voltage supply system (2b) are DC-isolated from one another and connected to one another in a signal-transmitting manner by at least one coupling element (3). The second voltage supply system (2b) also has at least one electrical switching element (5), which is electrically connected to the respective coupling element (3), for a load (6). In order to measure a current flowing to the load (6), the on-board motor vehicle electrical system (1) has a current measuring arrangement (7). According to the invention, the current measuring arrangement (7) comprises at least one Hall sensor (8) which is electrically connected to the first voltage source.
