Hi, I recently purchased a used makita 6100r generator and when checking it out I discovered on my 30 amp 220 receptacles arent getting full power. I took out the receptacle and checked the wires in back and I'm still not getting full power. My 110 and 20 amp receptacles are ok. Would this be a condenser problem? Thanks in advance.

Maybe I didn't explain this right. The generator isn't powering anything. It's just running at high idle and I checked the receptacles with a multi meter. It has 3- 220 receptacles and 1-110. If that generator is not powering anything it should have the correct output to each receptical. Maybe I didn't explain this right. The generator isn't powering anything.

Sorry, had to grin- yes, it wasn't clear what your problem was. I agree, at no load, you should have at least the rated voltage and most will measure somewhat high. I would first try a moderate load since it may be exxceeding an overvoltage limit briefly while running up that is causing it to disconnect. Try it with a moderate load of several hundred watts if you haven't done that yet. If it still misbehaves, it's time to start doing continuity checks and there may be a concealed fuse that has blown. Most units will have a resettable circuit breaker and then a fuse rated well above the generator's limit to prevent destruction in case the circuit breaker fails to trip as it should. Since this is a brushless type, it is using either a static or rotating field magnet. One I had years ago had extremely close spacing between the rotating magnet-equipped disc and the stationary field coils. The final death was due to the disc's bearings failing which electrically shorted the field coils and blew a fuse well above operating limits.
I replaced the bearings and carefully ground away the shorted areas of the field coil which restored operation but with a reduced output current capability.
