If you have 13V across the LED then it's reverse biased. Which is =
incorrect for the correct operation of the LED.
It should have ~1.2V maybe more (depends on manufacturer, colour, and =
everything else).

I hook the power to J3 and grd to J4. LED won't light up. I do have =
13v to one side of the LED and the other side has continuity to ground. =
Not sure what I'm doing wrong. The UEGO circuitry worked perfectly to =
spec. I'm just in the testing phase.
Thanks.
