I have a trio of 20 watt/12 volts halogen lights above my kitchen counter.
Every once in a while they just shut off for no apparent reason and then
come back on all by themselves within a couple of minutes (or a few seconds).
I believe that they are on the same circuit as the 2 AC oulets that are
in the same housing as the light switch. The AC outlets continue to work
when the lights have shut themselves off. So it's not a common circuit
breaker that's cutting out.
Sometimes flipping the on/off switch a few times seems to bring the
lights back on, but they might have come back on on their own without me
flipping the switch too. So, I sort of suspect the switch. But I can't
make the problem repeat itself by moving the switch in various
positions. The switch, for the most part, seems sound.
There are a pair of what look like AC adaptors/transformers that are
part of the system. The 1st one is connected directly to the AC. It's
hard to tell but the 2nd one is connected to the first one. I figure
that the 1st one is a transformer and the 2nd one is an AC/DC adaptor
(12 volts DC). They are screwed to the underside of the shelves closest
to the switch. Once or twice I've tapped on the 1st one of these and the
lights have come back on, but again they might have come back on on
Also, the two of the AC wires (one white and one black) going into the
1st transformer are held together with two of those, I guess you'd call
them, thumbscrews. I.e. The wires are held together when you turn the
thumbscrew a few times.
Obviously something is shorting out somewhere. But where?
I'm hoping that this is not a fire hazard. I really don't want to have
to call an electrician. I'm not totally inept but I'm not what you would
call a handy man either. I'm new at being a homeowner and have only been
in this house for 1 year.
Any tips, suggestions, etc.
