I am surprised no one caught this. I got to thinking about it and suddenly realized that if two leds were wired in this manner, they would effectively block each other, and no current would flow. I tested this on the breadboard and sure enough! Reversing either one of course instantly set things right and all was well. I must have misinterpreted the circuit years ago when examining one of these in a K-Line Mikado or whatever it was. And I assumed it was correct all this time. Sorry about that!

Hi Rod,

I have six of these circuit boards. Can you be a little more specific as to what I should wire to what to use them? I am not following the exception.

Thanks,

John
