serially to the + ?
That's practically the only way to measure it (short of using a series resistor).
Connect the meter in-line with the positive supply and the positive on the circuit.
Make SURE your meter can handle an amp or more.
If it can't handle that, you'll either smoke your meter or just blow a fuse.
