I reversed polarity on my battery, didn’t realize it. Put the trim up to remove the station bar. The trim worked. Put it in the water engine wouldn’t turn over. After putting the boat back on the trailer. I got home noticed the terminal crossed. Changed the diode, and it blew a 25 amp fuse along with 15amp. Changed both , trim worked as soon as I turned the engine over it blows the 15 amp fuse. What am I missing? 2024 mercury 50 horse
