Re: 24V+ Isolated Ground Leak



I helped you find a potential problem with the two unknown wires connected to the negative side of the 24v PERMANENT BUS.

Did you trace those?

Hi Martin,

Many Amel boats have been modified (ours included) and perhaps this binding wire was for a piece of equipment that had a metallic connection to saltwater, but that piece of equipment is no longer there. 
For example we replaced the Calpeda Air con pump with a March pump. The Calpeda pump is all metal and has a bonding wire connected usually to the metal one way valve on the outlet. The March pump has no metal parts in contact with salt water hence no need for a bonding it is no longer connected.

Rather than a list of components, as I said many Amels have been modified, you should check and be sure that EVERY metallic part that is in contact with sea water has a bonding wire attached to it...and that bonding wire is connected to the rudder zincs.
