Re: Voltage Regulator-Rectifier
I heard of guys using the later year rectifiers on early years, but I've never heard or someone using a Yamaha reg on a Honda.
The biggest problem with rectifiers, and in my experience why the burn out, is the lack of a good ground to the battery. The back of the regulator is metal and is supposed to ground against the frame. After a year or two, the aluminum gets a layer of oxidation on it that makes the gound very weak. The rectifier, which uses the ground to determine battery voltage, thinks the battery is low and over charges in an attempt to get things back to normal. This usually burns out the reg or battery or both.
Running a ground wire to one of the bolts on the reg with a big round wire end that contacts the back of the reg almost always fixes the problem. As long as the system isn't too damaged. The over heating in the system also often causes the connector plug between the reg and the stator to go bad as well, so be sure to check it for melting or bad wires.
