I'm not making it sound complicated, I'm trying to figure out what
you're describing -- until the last post, you hadn't even confirmed for
sure there being a switch as best I can recall. I was simply trying to
elicit sufficient information if possible to understand what might be
the situation and red isn't a very common wire color for two-wire Romex
cable, so simply was asking to make sure that there weren't yet more
factors at play.
Still can't really tell for sure, but seems as though one of the blacks
must be the feed. But, still not clear whether you're talking of two
separate black wires at the switch or the two ends of the same black
wire landed on the switch. The connections at the switch really
shouldn't have come into play. IIRC, there was also an adjacent
outlet? I'd suspect the feed came from that direction and then went to
the light and on to the whatever the others power w/ one sidetrack to
the switch for the light. But, if the reds are dead, something else
must not be working, too???? If not, that still makes me wonder their
real purpose might be undiscovered and something different than you're
thinking...like another switch.
I don't have any further ideas on how to diagnose this from afar,
sorry...maybe someone else lurking will take a stab at it. Good luck,
anyway.
