OpenEVSE should come right up and cycle the contactor and run through the self test. There are a few things that can cause a failure to boot:


  • No AC power to AC_Input¬†
  • LCD 4-pin connector is reversed
  • Short on output will put power supply into protection mode
  • Fuses next to AC_Input on the board blown (labeled "bel")
  • Power Supply module has failed
