It is hard to diagnose via an email which does not have all of the facts.
One question about your electrician...With the 24v battery switch ON, and the 220V shore power DISCONNECTED (UNPLUGGED), did the electrician try to locate a faulty 24 volt item that is connected to the bonding system? If he did not try this, I suggest that you might need another electrician.
The most likely item(s) that I can think of that is/are 24 volt, connected to the bonding system, and might be faulty is/are the macerator pumps on the side of the electric toilets, and/or the salt water toilet supply pumps (assuming that Kristy has the electric toilets. You might try turning OFF the WC breaker which is located in the engine room forward bulkhead (on BeBe 387). Use a volt meter to ensure that none of the pumps are still getting DC current...If the 3 volt voltage disappears, you found the culprit. Next, you will have to isolate which pump by disconnecting one at a time. Let me know if this works for you or not...if not, I need to know all of your 24 volt items and I will try to come up with another suspect item.
Also (on BeBe 387), all of the bonding wires were routed by Amel to the gray water bilge ground strap, where they were soldered to the top of the ground strap. I'm not sure, but I believe that your boat was originally built this way...if so, there has been a lot of changes. Let me know what you can about how your boat was originally wired, or someone else on this forum with a hull number before Kristy 243, can answer this question.
