Common Grounding Point / DC Ground on a DS41

[pas366]

Hi



I am installing an additional new Inverter and need to run an Earthing Cable from the metal Inverter Casing (Inverter only Not a combined inverter/charger).



Where is the Common Grounding Point / DC Ground on a 2013 S/O DS41 ?



There are no external grounds on the Hull (unlike the DS42) and the only Anodes are on the Saildrive prop.



I cannot see any grounding/earthing wires on either the Engine Block or Saildrive.



I have the Electrical Schematics but this doesn't help



I know the DC Negative Buss Bar is on the Starboard hull in the Aft cabin but no sign of any common grounding point



Can anyone advise where I can locate this common Grounding / Earthing point please

i just did this in the ds43.. the ground from the case of the inverter goes directly to the same bus bar that all the grounds go to.. then from that bus bar you go to the motor and on our ds43 it goes from that to a ground thru hull .. i just set it up the way the previous owner had it and they knew what hey were doing
