I am trying to replace single pole switch with a programmable timer switch. Leads (black and white)on the single pole switch measures 25 volts while bare copper in the back of switch and white (neutral)measures 125 volts. I was planning to attach black from box to black of timer, green of timer to bare copper for ground and white of timer to white of box and cap the red by itself with a wire nut. Anything wrong with this wiring. Need help.
