2013 JKU Sahara.
Had some Gremlins I was chasing. Speedometer would drop out with no loss of power, random dummy lights, radio reset. Popped the hood and the negative terminal was loose enough to just pull off with my fingers. tried tightening the nut on top and way to much corrosion. Cut the wires and added a splice kit until my replacement heavy duty terminals come in. Luckily no corrosion or burn made it past the soldered joint. It fixed every issue I was having LOL! These OEM terminals are crap!!
