Today I did a bit of spring maintenance and fixed a few low voltage
lights that weren't working. I spliced in fresh connections and all
the lights are once again working. However, one light, a spotlight,
is now flickering while the others are all shining steadily. The odd
thing is the flickering light was not one of the ones I repaired and
is, in fact, pretty much at the opposite end of the line from the
repaired ones. To clarify, it's not the very last light, there are two
more path lights that follow it in the lighting sequence that are
shining steadily. Any clues as to what's going on?
If it is a bi-pin halogen lamp then I'd vote for a bad connection between
the socket and lamp. I've had probably a dozen low-voltage lamps like this
and such problems have been pretty common. For me, puck fixture failures
have been the worst and I'm replacing them with Mepla Alfit which seem a
bit better than the big-box trash I originally installed.
It could be the lamp. Are these outdoor lamps, or indoor? Do they all
share the same transformer or do they have individual transformers?
Assuming they are outdoor garden lights, I would look for the individual
connection to the power cable.
corrosion/bad ground/loose wire/faulty transformer
That's about all there is. In the back of the lights, there are tiny crimp
ons that are on the end of the wire. Those pass through plastic blocks, and
sometimes those get pulled out where you cannot see if the sleeve is
actually sleeving over the pin in the rear of the bulb. Or whatever
connector it is supposed to sleeve over. Minute inspection with a
magnifying glass is required, but since you only have it on one bulb, it
should be easier than looking at every one in the string.
I had a fire detector that I purchased recently that had this problem.
Slipped it on there with some needlenose pliers, and problem solved. When
you find it, I'm sure it will be something very simple.
A "DOH" moment.
