I have an overhead, ceiling-mounted,.tracklighting system which
consists of six 35W Halogen lights on a 9-foot track with a canopy
type, in-line transformer which is marked: I/P: AC120V-60Hz 1.5A, O/P:
AC 12V 50-230W. Been working fine for 2 years but suddenly died. After
making sure all connections were tight and of course checking the AC
input side (which was OK) I removed the transformer which contains 2
wires (black/white) going in and 2 wires (Red, larger gauge) coming
out. I just don't know how to check the output of the transformer to
see if I'm getting 12VAC out? Do I just put my test probes across the
two red wires? Or one at a time to a ground? Can anyone help me on
this. Thank you very much. (As you can see, I know very little about
electronics!)
It's probably a switchmode power supply rather than a transformer, they do tend to fail suddenly when they go.
If you have 120V in, the bulbs show continuity, and they don't light, the transformer is bad.
