In pack 1, we're encouraged to test the LED's and are provided with a battery pack and test board. I put batteries in, tested all 4 LEDs and none of them worked.
I verified all four batteries were installed properly, and still nothing.
I put 4 brand new batteries in, and nothing
I think it would be a bit odd that all four LEDs would be bad, so I'm leaning toward a bad test board or battery pack.
Is there something I'm missing?
