I've seen this topic elsewhere, but have specific questions. I crossed battery terminals and smoked my alternator. I've read it needs to be replaced. Check. I've read there is a fuse to replace, but do not know specifically where it's located. The boat turns over, but won't start. Thunderbolt IV ignition system. I've never had a hard time starting this motor. I'm not a mechanic so testing/jumping stuff isn't an option. What else should I consider replacing? Any help is appreciated.
