When calling for cooling, I am reading 24-25 volts at condenser contactor. That should be enough to energize the contacts competely. I saw that the original contactor was pitted, so I replaced it with a new one (right one) and I am still getting almost a low voltage signal that barely engages contacts half way. I can sometimes press the contactor manually and it will stay in. Possibly a bad transformer? Anyone else got any other suggestions?
