Non-contact voltage tester measures hot, multimeter measures 0 volts
My house has a cheap battery doorbell and I’m looking to install a wired ring doorbell. I pulled out the existing wires and they measure hot with a voltage tester but they measure 0 volts with a multimeter.
For the life of me, I cannot find the doorbell transformer, and the chime does not seem to have power and measure 0 volts as well.
I assume this is just a false positive with the non contact voltage tester?
