Your CCGX has a menu devoted to starting/stopping the genset with a variety of conditions. Whats missing is the device to tell the Onan to Start/Stop. I have a PLC (Programmable logic controller ) which produces the required 3 second pulse required to get my Kohler generator to start/stop. Once you find out what your Onan needs is all "Plain Sailing".

I have resisted the urge for the genset to be on "Auto" I connect via the VRM portal and start it myself. I always make it a timed run because i dont trust the internet. If it falls over and i cannot get to the stop button........... well eventually it would run out of fuel :)

Hi, My wiring schematics don't go down to the level you would need and antway the "Smarts" are the logic within the PLC. There are lots on Onans in Lagoon catamarans and some should have Victron systems. Sorry I can't be of more help
