went to autozone to buy a new battery and somehow the guy who helped me sold me a battery for a 7mge and not realizing the terminals are different, i connected the positive to the negative and the negative to the positive terminals and holy spark.. took battery back to autozone and got the right one.. came back and connected battery and no light in dash.. only head lights and gauges works.. checked all the fuses inside car and inside engine and none are blown.. did i blow something else? relays?
