I’m not getting any drop breakup when I look at the charge electrode (green LED) in the head

This could be caused by a few things but most likely just a bad grounding between the head and the controller

  • Check the connections on the blue coax cable that runs through the umbilical. It plugs into the Drop generator on one end and the bottom left of the CPU board on the other.
Blue Coax connects on the bottom left
  • Check continuity on the green ground cable that runs through the umbilical.
  • Check on the CPU board for the two red LED’s LED 23 and LED 24 and make sure they are both on.
Both Red LED’s should be on for High Voltage

The fault could be any of the above and also the Drop Generator, PSU or the CPU board.
