Warn wont work

First thing I would do is clean and retighten all the power lead conections.
Might be just a dodgy conection.

Take the cover off the solenoids undo all the connections, clean and put back together. Also do the same with the connections at the battery end.

I would think it is most likely to be a bad connection and this will fix it.

If that fails then you may have to look at the contacts in the winches motor. You may have had water in the winch at one time.

G/day Kev.Most likely to be an earth cable,Installers use a chassis bolt etc, and these are usually exposed to all sorts of stuff.Remove the connection and wire brush the contact points,lube and retighten, should do it.

Yeah, check your earth...
It will make the click sound with no action.

How often do you run the winch when not in use. We put these things through so much abuse and often let them sit there for months/years when not needed then expect them to work when needed. It only takes a small amount of water to do damage when sitting idol. I'm not saying this is what you have done but a timely reminder for those with winches to give them a test run to keep them working well. Spray it with wd 40 or similar to help lubricate it all.

Thanks for the replies guys. I've checked all the connections but being very unskilled at auto electricianing I forgot about the earth. I'll have a crawl around during the week and see what I can find.

Cheers

P/S You can check the solenoids with a 12v test light. Check if you have power going in to them and when you activate the Winch switch check if it is going out to the motor

If it's been in any river crossings the brass ring housing the brushes which is only pressure connected to the motor housing develops a bit of oxidization and causes similar problems.

Clunk is likely to be the solenoid engaging so I'm tipping no problem there.

Connections, earth or ring mount are likely problems.

SG Leslie recommend drilling & tapping the motor housing and screwing the brass brush housing to it to prevent the problem.

Also, who fitted it? Did they rotate the motor to get the drain holes oriented correctly? Or has it been sitting half full of water for months since your last river crossing?

You can make them more water proof. I'm pretty sure there are still instructions for a service on my website - which is still around but hasn't been maintained for a long time - I suggest you maintain winches much more frequently than the site gets updated :o). Must get the courier off it.... sold that yonks ago.
