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
