I want to add a dimmer switch to my dining room chandleer. Taking the plsate off her is what I have 2 romax cable coming in the black wire from both cable are attached to the light switch the 2 white wires aare jumpered together. And a ground wire attached to the switch. My dimmer switch has 2 black wires and a ground. I tried to attach each black wire to each on the dimmer switch, that didnt work. I tried too connect both black wiires to the one wire coming from the dimmer and the two white wires to the other black wire form the dimmer that didnt work either any suggestions......Thank You

The dimmer should be wired just like the switch that it's replacing. Black wire to each black connection on the dimmer, and the whites "jumpered" together. My concern is that if you wired it the other way (with the blacks on one side of the dimmer and whites on the other side), you have created a dead short and probably destroyed the dimmer.

When i first wired that way the switch iluminated but the lights would not go on. I will go to the store tonight and get a new switch and try it again. Thanks

Which dimmer are you using? Some dimmers care about the difference between the "line" and the "load". If that's the case, you might have originally had the two black wires reversed. Please check the installation instructions, or post the model of the dimmer here. I'm surprised that there's a pilot light on the dimmer, but no connection to neutral.

"I'm surprised that there's a pilot light on the dimmer, but no connection to neutral."

Neon pilot lights do not require a neutral to operate.
They 'leak' enough voltage and current through the load (bulb filaments in this case) to ionize the neon an illuminate the neon bulb.
It take 90 V to turn a typical neon bulb on, but far less to keep voltage to keep it on, and the current is less than 0.01 A (10 milliamps) for a small neon bulb.
