      Did you check your manuals for any fuses inside .

        No voltage

        Yes I did check for fuses and other things that I know that will cause it not to get current I also check the comatator and check brushes .

          Only thing I could think to do is start at the back of one of the 120v resepticals with a multimeter and start back tracking the wires back up through the wiring see if they get hot anywhere maybe a bad wire or connection hopefully if your not comfortable with that check continuity all the way back

              I'm no expert but it seems unlikely that both the welding circuit and the generator circuit would fail at the same time, I would look at the slip rings again. check that you have continuity between the brush connections and the slip rings. Check them independantly. That is remove one brush to check the other, and check the rotor windings for continuity and that it is not shorted. This as you know is Miller's advice:"Have Factory Authorized Service Agent check brushes, slip rings, rotor, stator, integrated rectifier SR2, and Weld Output control R1." If you are not comfortable or do not know how to make these checks then I would suggest you take the advice and take it to a reputable service person. Good Luck.

                On my old bobcat 225 g plus it had a main fuse slo blo if it didn't have good contact in fuse holder your weren't going to weld or use the generator .
