Default Getting .143 vac reading on a 20A circuit

I'm renovating a rental unit that was built in the 50's and has been passed through several owners over the years (many of which have done some pretty shabby "fixing" of various systems including some of the electrical circuits). I elected to replace the metal outlet and switch boxes with plastic remodel boxes since I the switches and outlets were in need of replacement anyway. As I was tracing out the circuits with my Fluke model 113 digital multimeter I happened across one that gives a .143 voltage and a continuous tone even with the fuse removed from the socket. I traced the two part wire back to the panel and found that the neutral has the neutral from another circuit spliced into it (whoever did it just removed about an inch of insulation from the neutral tied into the buss bar and wrapped the bare end of the second neutral to it and then taped it up - I suspect because the second neutral was cut too short to reach the neutral buss bar). I haven't removed the tape and disconnected the two to check the circuit again but could this be the cause of the .143 reading I'm getting?

You are getting a false reading from your digital multimeter and it is confusing you. Use a simple test light or wiggly and you will see that the circuit is dead with the fuse removed.
