OK, sounds like a good idea. But want to be sure I understand how my current system is working so I don't unintentionally fry something. Thanks.Why not add a switch in the system that would connect the battery directly to the foot switches.... Label the switch something like: Engine off windlass power.
The switch would normally be left in the off position, so the engine would have to be running to use the windlass. Then on those rare occasions like quiet hours or engine failure, then flip the switch on.
