Winch negative power cable run

assuming you had good conections there shouldn't be any differance voltage drop wise between the two methods, I would at least bring the neg cable onto a bullbar mount bolt, or similar. but I surpose you know for sure if it is back to battery.

Correct, in a ideal world, the extra earth won't pose a problem rubbing though, as its merely connected to earth

But to be honest, its not absolutely crucial either, as your start motor operates via the chassis earth, and earthing via the chassis is no real biggy, as you generally aren;t operating the starter and the winch at the same time

The main earth lead from the battery to chassis is same diameter or bigger than earth supplied with winch. The trucks done a lot of winching over the years

Thanks for for the comments. I had just installed my old winch on my new Puma and I earthed it on the chassis near the winch because I only had a short bit of cable left. After the first test run in the yard the motor destroyed itself.Now I have gone crazy and ordered a brand new winch which should come with cables so I think I might earth it at the battery lead connection on the chassis.
