you don't need to pull the neg wires out of their ducts, but only disconnect the neg wire where it is attached to the item (motor, relay, pump, nav light, fridge, etc...). One week should be enough....

Thanks Eric. That makes sense. So everything on the winches breaker on the 24V panel goes to the control panel at the helm and the breakers throughout the boat go to the motors and pumps directly. So I need to go to each winch and pump separately, disconnect the neg wire and see if the voltage between the pos battery pole and the bonding disappears. I think. I'm still wondering if the bond/neg connection is somewhere between a motor and the battery, how am I going to find it? I guess that means tracing every neg wire back to the battery. Ugh, most of them are in chases where they aren't visible. That'd mean pulling them out, checking them, and running them back through the chase. That might take me a month or two.😩

The breaker on te 24 volt panel does not control the winches and a number of other things. That breaker only controls the control relays. The actual hi load breakers are as note in my previous note,
