Yes, with a modern digital voltage tester they are too sensitive, if you have an old analogue jobbie with a nice old fashioned needle you can almost get a better average reading around 10 volts, but it does flicker a bit, by coincidence been testing one today which suddenly decided to work, I can only assume the coil contacts were a bit grotty from standing over winter
