Default Windlass installation connection

I have an 30 ft 86 Sea Ray Sedan Bridge. It had 2 - 5.7's with v- drives....
My winter project is to install a Lewmar v700 windlass (and rebuild the bow sprit area).
I got most the wiring run last week. The fly bridge switch installed and the breaker and contactor installed..no wires connected yet. I understand how the wiring system works....

My questigon is this. At the battery end, should I connect the big #6 wires directly to the battery? Or should I connect them at the battery switch?

I only have 1 switch. Off -1 -2 and both. 3 gr 27 batteries.

My concern is running the high current draw of the windlasd through the switch.
The windlass breaker is right near the switch, and the batteries, so it is easy either way.

Any suggestions?

Thanks
Rocky.

Why the concern about the switch? The current through it is higher when starting an engine.

I would wire the hot to the switches common terminal. Then connect the return to a good common ground such as the engine block near the existing battery connection.

I prefer to minimize the amount of wires on the batteriers as this can lead to issues with the connections becoming loose.

That makes sense. I hadn't even thought of the starter load. Good comparison.

Thanks!!!

Exciting, no but after adding more pictures as the project progresses it will be nicely documented. This will help others see what is involved when they are considering this project for their boat.

IMHO you want the safety of being able to shut off all of your 12V if you need too. This is easiest if you wire everything through the battery switch. There is a reason it is called an "Isolation Switch" .

The limitations to the number of ring connectors is based on the size of the post. You risk overloading the post on the switch by adding more and more components. You can install a PowerPost, which acts like a 'remote (Pos.) battery post. They also make Positive Bus Bars for the same purpose. I prefer to have batteries connected to switches and devices connected to a power post or bus bar. Much neater and easier to manage.
