HI, I just purchased an older boat with an inboard motor. It has a 1984 mercruiser 2.5L 120. previous owner (coworker) said everything worked when it was put away. put a new battery in and as soon as I hooked up the wires their was sparks and terminals got hot. Looked around a little bit more and noticed the orange wire going from alternator to starter was very hot and smoking a bit at both ends. thought it was back feeding or something through alternator so i replaced it but got the same results. Not sure what do check next. If anyone has suggestions or similar experience that would be great.
Also the power trim doesn't work, I get a click at the motor but nothing else. I figured the brushes might be dirty something in the electric motor but not sure how to take it off or go about this.
