A few years ago I installed a set of 5 "under cabinet" halogen light fixtures. These are the 12v 20 watt variety.
This week two of the 5 lights became inoperative - I suppose they "burnt out". I had two new unopened 12v 20 w halogens, that I installed in place of the burned out lamps. When I turned on the power, NONE of the 5 lights would turn on. I removed the "new" lamps, leaving 2 vacant sockets - and when turning on power, the three original lamps turned on. I took one of the "good" lamps and placed in it the socket that previously had one of the burned out bulbs, it worked fine. I went to the hardware store and purchased another fresh
12v 20w halogen...tried it.....no luck....same as before, all 5 lights were out.I note that the transformer indicates 12v......I also measured about
12v ac at the sockets. I did not handle the bulbs with bare fingers.I'M STUMPED........anyone have any idea of what's going on here? Any troubleshooting suggestions?
