Hi, Since you mentioned that you are using a CW-80, you might want to ensure it is not an early CW-80 which has common on Red. (no need to add that to the mix) Suggest quick check of the CW-80 with a meter, a bulb or look at the date code on the bottom. A correctly wired CW-80 will have a G#### or QC50OK for the date code. If you only have four digits (like 0305) then it likely has common wired to Red.
