Guys, I really need help. I opened up three recessed lights fixtures
and here is what I found that confuses me even more. Lights 1, 2 and 3
work OK and do not dim. Lights 4, 5 and 6 dim if more then one light
from this group is on. If all are on all three dim even more. Power is
on fixture and comes to the fixture #3, then to fixture 4. From 4 it
goes both to 5 and 6. I opened both #3 and #4. I measured voltage
between neutral and hot wires and between hot and ground wires when two
lights from the problem group are dimmed. Voltage at fixture #3 is OK,
120V between hot and ground or neutral. However, at fixture #4 voltage
is 60 V between hot and neutral, 60 V between neutral and ground and
120 V between hot and ground. What can be wrong with the wire
connecting #3 and #4? The wire is BX armored cable AWG12. And what's
the best and safest way to fix the problem? I would like not to remover
that wire since to do so I have to rip sheetrock in half basement.
However I can put another cable in parallel.
