Trying to resolve electical problem

Just an idea... Could the resistance, capacitance and inductance associated with the length of wire between the J box and the second can be acting as a filter at the frequencies generated by the dimmer? This would explain why the voltage would be higher when he installed the switch and eliminated all but the 60Hz.

It would be interesting to be able to measure the voltage on that wire at different points to determine if there are peaks and nulls like you find on an RF transmission line.

Is that really possible in a fished cable?
 
disconnect the 1st can and feed straight to the 2nd and take voltage readings


also, run a 14/2 from the switch to the 2nd can (temporary ofcourse) (run it across the floor) just to chk readings, connect to the 1st can then too, and chk readings, this will find out if your 14/2 in the ceiling is bad
