I have a doorbell camera that stop getting power I changed the older transformer I test the transformer with my multimeter and it does not read any volts when touching both terminals when I touch one terminal and a metal to ground with the other probe it reads 7.5 on each terminal but like I said when touching both no power 0. I check the main hot line and it reads 119.8 so I know the line feeding the transformer is good I changed the transformer twice what could be the issue?
