ianmayco68 Posted December 31, 2019 Share Posted December 31, 2019 Hi all , I have searched and read through numerous threads but I’ve come across both answers as okay, should the earth for a winch go to the battery or will a good chassis earth be okay? It will only be used occasionally to get me or someone else out of trouble. cheers Ian Quote Link to comment Share on other sites More sharing options...
western Posted December 31, 2019 Share Posted December 31, 2019 mine goes from winch motor to the winch bumper & chassis, never given me any problems, the soleniod is earthed back to seperate battery -ve terminal for the winch Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 31, 2019 Share Posted December 31, 2019 Both will work, but to the battery will give you less resistance, and less connections = slightly more speed, especially at high load, and less chance of corrosion causing issues later down the line. I would always fit direct to battery. 2 Quote Link to comment Share on other sites More sharing options...
TSD Posted December 31, 2019 Share Posted December 31, 2019 I reckon a good chassis earth at both ends will be fine for most people, most of the time. It might (probably will) have a slightly lower stall load and run a bit slower under high load, drawing a bit more power, and run a bit hotter. The separate cable isn't really separate of course, it's in parallel with the chassis connection in most cases (and if it isn't, why not?) but the quality of the connections may have a bigger influence than the chassis/wire size in a lot of cases. I measured the losses of a few winch isolator switches last year, but the results were so depressing I wanted to recheck them before I published them anywhere, and never go around to it. There's a surprising number of connections in a typical winch circuit (~12) so making each of them as well as possible quite important. 1 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 31, 2019 Author Share Posted December 31, 2019 Cheers all , decided to go to the battery as I’ve upgraded all the cables and the last thing I want is to do it again and after a another read of the destructions with my glasses on it says earth from the bottom of the winch back to the battery, which I missed before . cheers Ian Quote Link to comment Share on other sites More sharing options...
western Posted December 31, 2019 Share Posted December 31, 2019 My Husky winch has a earth bolt at the bottom of the motor, this bolt screws in from under the mounting tray, I don't know why it couldn't have been put on the top of the motor, maybe it to keep it away from the 3 main terminals.

Escape Posted December 31, 2019 Share Posted December 31, 2019 I always wire a winch back to the battery. As said above, that gives you less connections and so a better chance of having a low resistance. I did make an exception on a Tdci I recently fitted a winch to. The battery negative is crimped and hard to get a good connection for an extra cable. But there is a very good earthpoint close by on the transfer box, with a nice thick cable directly from the battery. So I wired the winch earth to that and double checked to make sure resistance was <0.1ohm from battery to winch. I wouldn't trust just any chassis earth point. As TSD says, a typical battery switch is more than that, but you do want one of those. On the same car, I needed to fit a battery main cut-off. Normally I would put that in the negative cable, but that would mean the current for the winch has to pass 2 switches. So I wired the winch cut-off in parallel with the main cut-off, both directly off the battery positive. Should be as good as it can be.

Arjan Posted December 31, 2019 Share Posted December 31, 2019 We run always direct cable to & from the winch and the battery. Any loss is not pulling power. 2 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted January 3, 2020 Author Share Posted January 3, 2020 Cheers all .This is the solenoid in the plastic box it came in , would I be okay to take it out of the plastic box and house it in the top of the wing ? Reason I’m asking is I’ve upgraded the cables and they now won’t fit the box where the exit holes are . Would like to fit the solenoid here . cheers Ian Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 3, 2020 Share Posted January 3, 2020 Perhaps, though it doesn't look waterproof to me, so won't last long. Quote Link to comment Share on other sites More sharing options...
western Posted January 3, 2020 Share Posted January 3, 2020 My solenoid is behind left front lights on top of the inner wing. Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted January 3, 2020 Author Share Posted January 3, 2020 The plastic case definitely isn’t waterproof, but the solenoid looks like it is and the wireless box to the left definitely is because I can see it . Quote Link to comment Share on other sites More sharing options...
