1973 johnson 115. <br />model 115ESL73M Serial 1388075<br />My engine won't crank. Have replaced coils,<br />starter and solenoid. Had running and would not shut off so took igniton swith apart and touched black w/ yellow wire to 2 black ground wires and sparks flew and it shut off. Now it wont do anything. Was told to check in line fuse replaced it still nothing. Could it be the power pack if not what could it be. Woould it make a difference if there is no brass bolts between wires on solenoid. Thank you
