Winch draining battery
Hi all. I installed a winch on my patrol a few weeks ago and it seems to have completely drained my battery while off. I've made the assumption it's the winch because never had a problem with the battery and my old man has the exact same thing happen a cpl of yrs ago when he put a winch on his gq. I will probably go for the easy fix and just install an isolation switch on the main power to the winch but I'm just wondering why it would do this. All the wiring is exactly to the instructions given. Any help would be appreciated. Cheers

Enjoying the trips
There is a load somewhere, a clip on amp meter will show if there is.
Or take the negative cable off the battery and touch it on metal away from the battery, if it sparks there is power being used somewhere.
Winches use no power at all when not winching in or out. Wonder if the brake is powered up and causing you a problem?

Brand new winch or second hand?
Does it drain the battery in a matter of minutes/hours or days?

How quickly does it drain your battery?
I would say it's more then likely a problem with your alternator draining the battery when the engine is not running then your winch.

Thanks for all the replies guys. Hadn't had a chance to get back to it till now. It's a new winch. Just one of those aldi winches. It's deffinatly wired correctly. Pretty hard to get it wrong really. All the cables from winch to control box are marked as are positive and negative to the battery. It seemed to be draining over a period of around a day. Hard to say for sure as I don't drive the old girl every day. I've replaced the battery earth cable and terminal and cleaned up where it goes to so will see if that makes a difference

If it it was the alternator as yendor said I imagine it would still drain even if I disconnected the winch from power??
