If that engine still has what is called a clipper switch, remove from the system. In the OMC repair manual under trouble shooting guide as I recall, it will say, if engine blow's main fuse, and continues to blow fuse, replace clipper switch. That switch does not need to be in the system. If the pulse pak is being replaced, they advise removing this switch. Rapair will not honor the warranty on the pak if this switch is left in place.
