A friend's situation is his Track lighting, in a hallway with switches at
each end, has stopped working....
Historically only one wall switch worked since moving into the house and
only when the opposite end wall switch was in a specific position. Recently
a guest flipped the wall switch and the Track lighting no longer works from
either end in any combination of positions.
I corrected the misconnected 3 wire cable between the wall switches. One
switch had the 2 "travelers " reversed.
With the track lighting transformer disconnected at the ceiling junction
box, the wall switches now operated properly, applying power to the
With track lighting transformer reconnected to both the track and ceiling
box power source, the track lights didn't work..
A voltage check at the transformer output confirmed the 12 volt ac but no
voltage at any track lights. Light bulbs checked good when removed. Since
logic indicates a lack of electrical connection at the 2 conductor bus,
contact points were cleaned up but to no avail.
Any help would be appreciated as I'm lost <G>. Thanks, Dick
