Hello my name is Dave. I have a 1984 75 hp johnson evinrude outboard. Was running now have lost spark. Found loose ground wire on Black control pack on right side of engine looking from the back. Could i have burnt it up? I have power to the motor, brand new battery. I had it running in driveway and then just fell over. Help with any tips on how to test for spark or other things relating to spark please. thank you.
