I have two dimmer switches in the same box side by side. one goes to three pot lights, the other goes to a halogen track light. these have been working for 5 years. the lights have burnt out and been changed and everything worked fine. one night the little green light on the track light went out. I've flipped the breaker and tested all the wires with an eletrical reader pen, switched the light dimmers and all the light bulbs. and still the little green light won't come on either will the tracklight. the lights still have power according to the eletrical pen reader. whats wrong?

Sounds like the transformer in your track light. In the box where the green light is, the voltage is converted by a small transformer from 120v to 12v for the halogen lights. With the breaker off, try jumping out the dimmer going to the track light (disconnect the dimmer and connect the two loose wires from box together). With the breaker back on, if you have 120v power on the wires (black/white) going into the track light transformer (measured at the track light), and the green light won't come on, I'd say it's the track light transformer. You may have to replace the whole track if you can't get the transformer as a part.
