Kent, I have a 54, but I suspect the SM is the same. My A/C pump control box is located on the portside wall in the engine room, opposite the generator. I know because I just removed it to make room for my new inverter.
You should not have 120V unless you are connected to shore power in the US. One of the 240V legs to ground will give you 120V.

I just checked again Bill. There is 124 VAC between either blue or brown at the pump and either the AC ground or the bonding system. There is almost NO resistance between the AC ground and the bonding system.
There is at least a solid connection from AC ground to the bonding system. Any idea how to figure out where that might be?
Do you know where the relay box is that powers the AC pump when the units are turned on? That's where I think at least part of the problem lies.

I think that you just said that there is no voltage between brow and earth with the breakers off
And that there is voltage between the brown and the bonding system green/yellow under the exact same circumstances.
If this is true, I believe that your bonding system is HOT. Check between bonding system and earth (green/yellow from shore)
