Under some circumstances digital volt meters can read "ghost voltage". This typically occurs when there is no voltage at all on the probes but there is voltage in nearby wires. Ghost voltage is usually unreasonably high.
Best solution is to use a very low wattage light bulb across the points you want to test and the meter leads across that. If the high voltage is real it may blow the bulb so be careful !
Exactly correct!
