Hi there, Try following the pictures in the first link to see if you have the hidden 15 amp fuse. It's a 50/50 if you have it or not, if so, it could be your problem here.
If not, I seem to recall that some of the sea ray model boats (Not all) where setting up their ignition power system a little bit different then the standard way of doing it, so yours may be a bit more difficult to walk you through it then usual to where, if you can't seem to find anything obvious, you may need to seek advice from a "sea ray" technician that knows the ignition system well.
Or another option if needed could be that "I believe" there may be some "sea ray" manuals over on club sea ray that offers some "sea ray boat" service manuals with wiring diagrams.
