Crazy thing happened today while I attempted to climb the rock pile at the grand reopening of OK4x4 in Stewartsville, NJ...I slid off a rock and took a nice jolt. The emergency flashers went on and will not go off! They stay on when the key is turned off and even remain on when the negative battery cable is disconnected (must be due to the ground for the winch?) They do go off when the positive cable is disconnected. They will not even go out when the fuse is removed.Any ideas before I take it into a RR dealer? 1995 LWB.
