It doesn't really sound like a "bad" LED. They usually work or they don't. [:)] <br /> <br />I wish I was more familiar with the engine, but it sounds like a polarity/wiring issue. You seem to be completing the circuit by touching the LED, but I'm just not sure what's going on. <br /> <br />When you say the light works on DC but not DCC, are you actually moving the engine directy from a DC track (where it works) to a DCC track (where it doesn't?) <br /> <br />I'm not doubting you, just trying to get a handle on your troubleshooting method. Finding electrical problems are tough and it involves isolating each element and finally narrowing it down to the problem. <br /> <br />If I were tackling this, I'd verify that the LED works on a DC track, in forward and reverse (I assume it's wired directionally.) Then immediately move it to the DCC track and see if it works in analog mode. Forward and reverse. <br /> <br />Then in DCC mode. Forward and reverse. <br /> <br />Then I'd put a regular bulb back in and repeat the above. If it works fine with the bulb but not the LED, then it should be a polarity/wiring issue. <br /> <br />Mike Tennent
