1. Set your volt meter to DC voltage at whatever range is greater than 12V (e.g. 0-20V, 0-50V, or 0-100V).
2. Firmly connect your negative lead (usually black) to either the negative terminal on your battery, or a good frame ground.
3. Start touching wires or terminals with the positive lead (usually red) until you find what you're after (meter reads 12V with the engine off or 13-14V with the engine running.

What are you adding to your bike?  One or two of us might have ideas about the best place to take power from.

You want to use a setting that will provide >= 12VDC. 

Easier yet - pick up a test light - it's got a probe on one end and a clamp on the other, lights up when you hit a hot wire.

I have one of those tucked away somewhere. Thanks.

What Gryphon said.  Good description.  Make sure the black wire is in common and the red one in volt/ohm, not amps.  Some types of meters have several places to plug in the wires.

Make sure your meter is set on DC Volts.  If you set it on DC Amps, you'll need extra fuses for your meter.
