The
anchor windlass is typically wired to the main battery banks located in close proximity to your engine compartment. A circuit breaker and controller should also be wired between the batteries and
windlass. There are many variations for house & engine banks, so some investigation into the boat's electrical wiring system should reveal which circuit the
windlass operates from.
One important point - never attempt to operate an electric
windlass under load, without first starting the engine. This will surely drain the battery banks.
