    Simple electrical question

    I am trying to hook up an indicator light to see if I have power to an appliance.

    The appliance is plugged into an appliance module, so I am using an appliance module with the same code and have this plugged into it

    http://www.radioshack.com/product/in...ductId=2102794

    The problem is that when power is on the LED is bright, but when power is off it still shines but not as brightly.

    Am I using the wrong LED? Bulb? do I need something else? ( resisitor?)

    any help appreciated.

    I'm assuming X10 Appliance module. I think what you'll find is the local voltage sense is allowing enough voltage through to light the lamp, dimly anyway. Most X10 modules keep just enough voltage going through to allow the module to sense when you have turned on the appliance manually and allow it module to turn on. I have seen some mods for Appliance modules that disable the local section. I've not tried them though.

      The device you have is not a led, it is a small neon light.

      it is sensitive to low current and will pickup the leakage current from the current sense circuitry in the appliance module. You will need to Modify the module like Nightwalker said to get rid of the dim flickering.

      You can search the forum to find info about the mod. It's been discussed around here somewhere and somebody even posted photos. If I remember correctly, you need to cut a diode wire to disable the current sense.

      Remember, however, that you are dealing with live line voltage. Insulation is very important...

        Thanks for the replies.

        I'll look for the mods aand try it out.

          Instead of the Neon indicator you can buy a conventional "pilot lamp" like this. (you can find them at Lowes or Home Depot). I use this for a "towel warmer" to tell me when it is ON. You could also try a "fixture module" instead of an appliance module. The fixture module does not have the local current sense feature.

            You could also just disable the local current sense feature of the module.

            It's easy to do...I don't have the link handy...but it involves clipping a single DIODE inside the module.

              There are at least two versions of the X10 appliance module.
              I think this may be the older version: http://www.laureanno.com/x10-mods.html . Look at "Modification to disable local control/current sensing"

              With later versions, which is likely what you have, you'll find a simple jumper flush with the component side of the board which needs to be cut to accomplish the same thing. I've modified a couple of these successfully.
              http://www.idobartana.com/hakb/Modif...nce_module.htm . Look at "Modifying appliance modules for local control". Instead of adding a switch, you just want to cut the jumper

                    Another option that I have used is a neon or LED night light. They draw very little current, do not light when the module is off, and are easily visible, even in day light.
