Winch Power Cable

Hi, just currently collecting bits to wire up my 10,000lbs superwinch.

www.superwinch.com/products/productdetai...3.82806.0.0.0?pp=12&

Planning on a 200amp split charge relay and fitting a large truck battery in the boot. Just wondering what size cable to run between the winch and battery considering the max line pull is rated at 350amps. It seems most cost effective to buy a quality set of jump leads just for the cable. Im wondering what others have used?

A good cheap option is a power cable from an accident damaged e46 bmw, they run the length of the car so are plenty long enough, and when a bmw is in an accident it blows a small airbag connector off of the end rendering them useless for there bmw purpose, so secondhand should cost you very little, there are a few different ones increasing in size for the diesel versions but even the petrol persion has a very thick cable, hope this is of some help, but as a said you would want a lead with a blown end from a breakers as undamaged ones are fortunes.

Oh No, No, No ,No, No!

That winch could draw 300 amps under full load! So BMW power cable will fry!

You need 50mm sq power cable or some people use thick welding cable - see:

www.vehicle-wiring-products.eu/VWP-onlin...ble/batterycable.php

for suitable cable.

Do Not skimp on winch power cable or at best your winch won't work well and at worst you'll have a little bonfire in your Jimny!

Use a proper Isolator too and proper connectors. None of it's cheap but neither is a burnt out Jimny!

Couldn't agree more, and also run the negative back to the battery as well. Don't rely on an earth through a bolt locally to the winch.

Thanks Robert, great link, they seem to have everything I need to make up a split charge system and power to the winch. It's going to be an expensive install but don't fancy ending up in flames! I cannot believe the previous owner had run the cables straight to the main battery and had not fried it, or shorted the positive connections to earth ( I should have taken photos !) Dangerous!.

I'm considering buying these 50mm jump leads as I can chop off the croc clips and the cable is of correct spec, also it works out much cheaper.

how about this it will be about £30 cheaper than buying them booster cables for the same amount of cable
