I have a 2011 Ranger Crew 500 efi and was installing a winch. While doing so I accidentally arced the bottom two screws of the row of three screws on the drivers side under the hood on the frame. What are those and is there anything I should be worried about? I checked all the fuses and they are good. The units starts and drives well, without any engine warning light or other problems except there is a clicking sound around the engine for a few seconds after I turn it off, which may be new, or may not as I don't remember it happening before. Anyone's help will be greatly appreciated.
