Install dimmer on 3 way system
I am not an electriction so forgive me of I don’t use standard terms. I have an old home and two switches that contol a light in my lanai. I purchased a DVCL-153PR dimmer. One switch has a black, red, and white wire and the other has the same with white wires connected in switcg housing and black wires connected same way. I presume these are the wires from the light conecting to the inside of the switch housing and then the same red, black and white wires are connected to the switch. The red, black, and white wires look to run to the switch I am trying to replace. No grounds are attaced to any switch but are in each box. When I hook up new switch it get off and on but no dimming. Help? What am I doinf wrong.
