I have a 1983 115 hp merc with power trim and tilt. While not paying total attention when re connecting the battery I reversed the pos and neg. Of cource I saw a small spark which reminded me that I now have toasted the battery. However after purchasing a new battery and hooking it up correctly this time, I have power to my running lights and horn but no starter or power trim functions are working. Any ideas about what I can do to fix the prob? Thanks...
