Hello all.
I'm trying to make a dead simple tank circuit and test its frequency using either my multimeter (which has the Hz measurement) or my oscilloscope.
Now I've never built one of these circuits before but it looks fairly straightforward, however I've had no luck so far in generating a measurable frequency in the LC circuitry.
My understanding is that I can use something like this:

When I try to hook this up I see 0 Hz on my multimeter.
Here is how I have my circuit: http://imgur.com/lvhgZfT
The green is the path for current to flow. The capacitor is light blue but visible. The coil/capacitor loop actually connects back via the breadboard to the place where the positive terminal connects to the coil.
