I have a three phase alternator and I used a digital voltage meter across the output terminal and the reading went from OL to 4000 volts to 3000 volts and quickly decreased to zero volts, then went through the range again starting from OL. It continued to do this, I thought the meter could have had a fault so I used another volt meter and the same thing happened. What would cause this?
