The track is getting power( i checked with my voltage meter), but the lights will not come on, this is a 12 volt system. Very confusing
May I ask YOU a question? Where did you check with your voltage meter, and is the track lighting new or existing? If you are getting 110 / 120 volts AC at the ceiling box, but no lights, your transformer could be bad, or you could be installing the lamp bases 'reversed' from what the DC lamp requires. Quick note: The AC current is converted to DC, which now 'polarizes' the wiring into positive and negative. If you reverse the leads, you will get nothing. Look closely at the lamp bases that rotate into the track. One lug is usually larger, and one lug lower. Look closely at the track to ensure your base is contacting the conductive copper bars in EACH of the tracks. While you might be able to seat the lamp base, you might also be missing the contact required. If the tabs on the base are properly contacting the conductive bars, check to ensure you have 12 volts DC between them. If so, then check the seating of the bulbs in each lamp holder. I once installed a system that had an intermittent transformer, and when we finally got to the root of the problem, the manufacturer shipped out a completely new unit. The old one is now retired Hard to diagnose over the net, but I hope this gives you a place to start
