how do i easily isolate the sparky bits for my winch? from memory it draws up to 450amps.
i have had a bit of a look around and haven't found anything over 200amp.
so whats the go? what should i use?
Narva Part no. 61090
310A at 12V continuous load maximum
500A at 12V for 5 minutes
I know repco and the like can order these in.

I don't know what they are worth, but 61075 cost me about $120 last year, so i'm guessing it'll cost more than that.
Another avenue worth investigating would be the screw type isolation switches mounted directly on battery terminals. I think I have seen them in supercheap but they probably aren't rated to 450A and that would isolate everything - not just winch. Why do you want to isolate the winch when they already have a solenoid box that does that?
