    Good evening all. I just purchased a 2000 Nitro NX750, with a 125 hp Tracker marine outboard. I’ve spent 2 Days so far going through/cleaning boat and motor and came across the burned up connection on the regulator. It appears one of the 2 yellow wires going to the flywheel, is the culprit. The others around it are melted as well but not near as bad. The guy I bought it from started it up twice for me (with muffs) and it seemed to run fine. As far as I can tell, the regulator & flywheel both look fine. Anyone else ever came across this?

    Sounds like the voltage regulator is shorted out. Check to see if you are charging when the motor is running. The motor has to be running above idle 2000-3000 rpms. Check battery voltage before starting and then while running. There should be a voltage increase if the regulator is working.
