What solenoid to use. I use a DC Power Contactor. I've been using Stancor 586-902's a long time and they work well and are reliable. Contact material is a silver alloy, not copper. The inrush current rating exceeds (600A) what you can put through an F3b winch and the continuous duty (200A) is in the range of what flows through a winch. They are a little larger than the auto solenoids most of you are familiar with and they are more expensive.
I usually purchase them from Newark Electronics.
