I am putting in a small bilge pump in my 20' flatbottom river boat.
Currently there is no electronic stuff on the boat other than starting.
Should I wire directly to the battery or put a bus under the console? I am adding navigation lights later (next winter probably).
I was planning on going from battery to switch directly, but then was thinking it could get messy and I may larger wire. I planned on going from battery to switch with inline fuse then from switch to pump.
This is about what I was planning:
If I connect directly to battery what gage wire should I use? I am assuming I would need to calculate length / current drop to determine wire size. As far as wiring I have the cold weather stuff from NAPA but do I need to get weather resistant? This stuff is pretty tough!
Also, for the pump do I connect ground wires to negative for pump or to ground (Boat).
Thanks for helping a newbie ! !
