Check main fuses and DCBUS voltage. Verify DC BUS voltage present in Gate Cmd board (neon ON) If neon off, Verify DC BUS voltage present in rotation board (neon ON) If neon on, verify cabling to Gate cmd board. If neon off, check fuse in ACDC board. If fuse has blown, check if the DCBUS input to rotation board or Gate cmd board is in short circuit and replace the Rotation board or the inverter. If DC BUS ok, run Inverter gate command diagnostics If test fails, replace PPC kV control board (first) or Inverter
