Looking to install an ecobee thermostat and decided to measure my common wire before unhooking anything. I tested the R, C wires and see they are only reading 14v, whereas R,Y, and R,W are reading 28v.
I traced the wires from the HVAC board and do see a blue and red wire coming from the C terminal. I then traced the red wire and it looks to be going to the condensing unit, the blue wire does lead towards the thermostat, however, each end is coiled around itself at the splice.
Would it be okay to splice the two blue wires together to make connectivity? Or, is there a specific reason that it would be configured this way.
