Im not sure if it was moisture or interference that caused the issue, but after my grizzly sat in the garage all weekend, something triggered the winch in the middle of the night and it ran until it fried the receiver that is located inside of the black box.
I took it apart and have pictures but they arent on my computer for me to upload. It was scary, I opened my garage door to head to work and couldnt see for all of the smoke. It very easily couldve burned the garage, and house down while my wife and kids were inside asleep.
I just wanted to give the new guys a heads up here. The winch still operates fine, but the controller is junk, I found several instances of other people having similar issues, I think mine was caused by interference from my garage door opener or the wireless baby monitor.
Either way, the easiest solution is to put a disconnect on the hot side that can be turned off when the atv is parked.
