I have a 1978 mercury 50 hp outboard.
One wire (a big red one) attached to the rectifer has heavy corrosion and looks bad. From my manual this is the wire the heads to the + side of battery and cannot be working very well to charge my battery. I thought of splicing a wire in but was told by many this is a bad idea. It was recommended replacing the internal wiring harness. I found one online for about $100 bucks. didn't seem too bad. Is it difficult to replace? Where does the other end of the harness plug into? It appears from the pictures to have a brass prong plug on one end this is the end I do not know where it goes. I was thinking I need to replace the rectifier while I am at it.
What controls the rectifer output so the battery does not get over charged?
Thanks
