7 volt? The rectifer is in the charging system. It is after the stator but before the regulator. It has three yellow, two green, one red and one red/white wires going to it. When I ohmed it out, forward and reverse bias, I did not get the readings the book calls for so I am replacing it hoping it will fix my no charging problem. I have already checked the stator and it's good, I have continuity between all three yellow wires and no continuity between the three yellow wires and ground. So if the rectifier doesn't fix it, it will be onto the regulator.
