I recently installed a new bathroom fan where there wasnt one before and along with it I also changed the single light switch that was turning on/off the 2 seperate lights with a dual lightswitch and put a fan timer beside it. Making the box bigger for 2 switches of course.
Now the fan and 2nd light doesnt turn on unless the top switch is on first. Maybe this ms paint picture I made can help show what I am doing wrong.
Oh this is an older house too as it still even has knot and tube wiring though I think its not hooked up as I dont see any wires attached to it from the spaces in the ceiling I made elsewhere before.
