Please help if you can... I just replaced some old 3-way switches with new Maetro+Controller 3 way dimmers. I did this on 2 light separate lights (I.e. changed a total of 4 switches... 2 of these: Lutron MA-R-WH Maestro Companion 120V 8.3A Designer Digital Dimmer Switch and, 2 of these: Lutron Maestro C.L Dimmer Switch for Dimmable LED, Halogen & Incandescent Bulbs, Single-Pole or Multi-Location, MACL-153M-WH
I got the same behavior on both circuits. Here is the problem. When I was done wiring up, the lights looked a little dimmer than before (everything else worked perfectly). So, I measured the voltage at one of the 4 chandelier bulb sockets where I got a voltage to ground of 100VAC!!! Bizzar! There is only one light being controlled on each dimmer circuit (a chandalier with 4 small bulbs...I.e. low load). So, I measured the voltages along the circuit. Here is what I found:
Power leg into first dimmer: 120V
With the light turned on, the voltage on the same dimmer: 100V on one connection and 107V on the other (pretty sure the 107V is the phantom voltage).
3.The voltage on both powered legs of the 2nd dimmer is 100V--I.e. 100V from the first transformer and 100V on the line to the light fixture (107V also on the secondary connection/fantom?).
As mentioned above, I have a second light that I also changed the switches on. Same power coming in and same neutrals. I got the same result. I disconnected the second one to see if it was impacting the first... it didn't seem to be).
Thoughts?
Thank you in advance. Dave
