Your problem may be an indication of something much more serious.
How long have you owned this Amel 54? Has there been an engine change, or any sensors changed?
When Amel installed the Volvo D3-110, it had been modified to be Isolated Ground by Volvo France. If you ask any Volvo dealer to check the serial number for such a modification, it will not show up on Volvos database. In fact, it is difficult to find any Volvo record of this modification which occurred with 100% of all D3s installed when the 54 was built by Amel.
I believe that your Isolated Ground has been defeated because of either:
Yes, if any of the above are true, when you disconnect the 24VDC Negative from the 24VDC Alternator, you will remove the fault indicated on the Bonding test circuit.
I consider this issue serious and you should seek expert help. A defeated Isolated Ground has been the cause of ruined C-Drives and other serious issues. Until you have this resolved, you should add a propeller zinc, although that will not completely protect things.
