When I am not using my boat, actually the first thing I do when I pull
it up onto it's trailer, the 'traction' circuit is isolated. I don't
actually have a battery disconnect switch, as my batteries are easily
accessible on my boat - I disconnect power the lead from the batteries.
My charger has it's own separate connection to the battery pack. My
primary reason for doing this is to make absolutely sure the motor can't
start (say some one bumps the direction switch while getting their gear
out of the boat) and cause possible safety issues with the prop spinning
when people might be able to come in contact with it. With an 'air gap'
in the circuit I KNOW it's impossible for the motor to start.
This also disconnects the 'pre-charge' resistors from the circuit, as
I have them wired across the terminals of the main DC contactor.
