Adding an anchor windlass to my Islander 270. I have 3 batterys and 2 battery switches. I can easly connect to the dual starboard batterys but would like to wire the positive lead into the battery switch so that when I leave the boat and shut the switches off everything but the fridge and bilge pumps are off. Wondering which of the 3 posts I should hook into. Any suggestions?
 
When you turn a battery switch to off, is your engine power then shut off ? If so, connect the lead to the same terminal your engine lead connects to on the battery switch. You need to add a circuit breaker to the lead in the transom, as close as practicle to the battery switch.

I recommend waterproof switchable breaker.
 
To add onto what Bob said use a breaker within 6-8" of the unfused connection. This is the safest option. I like the Blue Seas breakers they trip and reset well. They are expensive, but work and last. If it were me, I'd use a connection on the battery switch output for a motor. The windlass motor can pull the voltage quite low, enough to cause electronics to reboot (some electronics can be damaged be repeated low voltage and surging) for that reason use something other than the house bank. Usually I have all my elecronics and engines fired before I raise the anchor so rebooting my GPS, radar, fishfinder, depth right as I'm pulling away does not make sense.

On my boat the wiring comes out of the port rail so I used the port motor battery. jh
 
Windlass is in. I used a test light to find correct stud on the battery switch.
It is a Lemar Pro Fish 700 and came with a 40 Amp Breaker that I located about 1' from the battery switch.
Thanks for the advice.
 
I used the single port side battery. GPS, radios, depth finders, Fridge, etc etc are all on the 2 starboard batterys. I use only use one engine to troll with and with only 2 down riggers I deided to spread the load. They don't really use all that much current and we are not running them up and down all that much anyway.
