Did an inspection and noticed the top rectifier was burned up on my 96 150 mariner. The bottom rectifier looks to be getting hot too the solder in the circuit is melting. I just want to know if the rectifiers just go bad or could their be something causing them to go bad like the stator. I did a resistance check on the stator and its within limits. The coil windings look good too nothing burnt or discolored. Id hate to replace the rectifiers and them burn up again.
