...and I don't know what happened. 

I had the last 30 nodes or so of a string not light all of a sudden.  I suspected a node went bad.  I removed the first node that didn't light. 
Then I had this idea - what if the node just before (last lit node) was really the bad node and wasn't passing to the next node. 
So instead of patching in a new node right away I soldered the last lit node to the next node.  I turned on lights and the last 29 nodes still didn't light. 
I went and got my volt meter and placed it on the ground wire (green) and the 5V+ wire (red) and WHOA! - all the lights that didn't light suddenly turned on. 
I then replaced the "bad" node I clipped out and the string still worked.

Any idea why when I applied the voltmeter the strand completely lit up?

Opps. It was late and I was tired.  12V wire.  I'm using Ray's nodes.
