Sounds like you shorted the LED out if you went from signal wire to ground (parallel with the LED?) What do you mean by 10rj? If it's 10 ohms, that's probably way too much, but I've never done LED resistors before, so I may be all wet. The resistor needs to be in series, according to the web, so signal wire to resistor to LED to ground. Or signal wire to LED to resistor to ground.
