Correct!, which means when he added a resistor the voltage drop was far beyond the needed voltage to illuminate the LED. Damn' the missing link!

Dont send it to your friend!!!!!!! lol you can do it

i tried it without the resistor too guys...sorry lol.

i read the voltage across the front of the gauges while they were in the car...it was like 11.9v

its internally resisted

Same would apply bro. The resistor is most likely built into the board rather than the stock LED. Which means if you add a resisted LED there's a severe voltage drop equaling no illumination.. And if you added another resistor to that there would be nearly 0 voltage presant on the output (-) side of the LED = no lighty uppie..
