To perform a parasitic draw test (checking for battery drain with the vehicle off), how should a digital multimeter be connected to the circuit?

1. Set the meter to DC Amps and connect it in series between the disconnected battery cable and the battery terminal post
2. Set the meter to DC Volts and connect it in parallel across the positive and negative battery posts
3. Set the meter to Ohms and connect the leads to the alternator housing
4. Set the meter to AC Amps and connect it in series with the radio fuse
