That would work for sure. Just not something I would choose to do at 4 am in the Gulf Stream
with no nav lights and trying to keep my distance from cruise
ships if I could avoid it for $35.
It took me an hour to get at the back of my switch, I was on dry land, the boat was not pitching, and I had lots of light. Some boats it may be easy to access these terminals.
To jumper the switch terminals the battery banks wires would also need to be disconnected. If your alternator
goes through this switch it is now toast.
The point of the post was if you have a switch like this be aware it may fail at a bad time. A sailor may want to replace it now to avoid this problem, or keep sailing and wait for it to fall apart.
