With a multimeter set to 10A (10 amps) current mode

....disconnect either the positive or negative battery cable from the house battery and complete the circuit by placing the meter inline between the battery terminal and the cable, so one lead on the battery cable and the other on the battery terminal. When the meter is set to current mode it's just like a piece of wire...it's lets the current flow and gives you a reading
Note the current reading....if the reading is less than an amp you can switch the meter to ma (milli-amp range) for a little more accuracy, although likely not required.
