Bought a few used and new SR227 X-10 wall outlet modules. Tested them
separately before installing by hookup to a line cord. All was well. Wired
them into a duplex outlet box at the end of a run, pigtailed together and
they (I think it's only one, actually) started chattering.

I've read X-10 appliance/wall socket module chattering is almost always
considered a mechanical issue, but why would they test cleanly one by one
and then chatter when in place? This is without a load plugged in. I
tested with a floor lamp, although perhaps not without a load in place.

One other difference is that they are installed face down in the basement
ceiling but I can't see orientation having much to do with it. They are
also set to the same housecode, but that shouldn't matter much. Happens
with both an XTB boosted and unboosted mini-controller. Hit ON and you get
four rapid clicks from the wallbox.

Any thoughts? I am going to have to unwire them (what a BITCH!!!!!) unless
putting a load on the units or some other easier fix makes the chatter
vanish on its on.

The chattering probably means that little plastic piece has broken. Maybe
it had just enough life left in it to get past your initial testing. I had
one fail rather quickly here, but another is still working fine after 4
almost years.

"almost 4 years" Sorry for the typo.

I'm going to first plug in loads to both outlets, then switch the units
codes and then yank the units. Throughout the years I've seen chattering
come and go in various modules so I am more than a little curious as to
whether this is just a cam issue or some interaction problem. What torques
me the most is that I *could* have easily tested them in tandem before I
installed them. It will be interesting to see if it indeed was on its last
legs and just happened to break *after* I climbed the ladder and screwed
them in tight.

Could this be mechanical stress on the modules that was absent when you
tested in "free air"?
