Image of circuit

The wire is attached to the bottom of each D battery. I already know that I have to put the bottom of the light bulb on the positive side of the battery.

My multimeter looks like this: Multimeter

I'm not sure where to put the testing probes. I don't think this is important, but the wire is made of steel wool.

I hope I can get some help.

If you trying to measure voltage, connect the black connector probe (Terminal) to COM. Move the rotatory switch 20 DCV. The dot should point to 20 DCV. Then place the black exposed probe to negative and red expose probe to positive button on the battery. You should read somewhere around 1.5V for the D size battery.
