On mine, (Onan 5500, gasoline) I have to remove the air cleaner assembly....simple enough, only a couple of screws,....and there is a plastic cover over where the brushes are. That cover on mine is the cover for the brushes. Remove that cover and you should be able to see the slip ring...it looks like white plastic with a brown/copper ring around it on the end of the rotor. You can probably see the slip ring good enough to shoot cleaner at it through the vent slots over the end of the rotor. Just spray some contact cleaner towards it while running. Be careful with the moving parts, though, so that you don't get the spray tube from the contact cleaner too close and caught in it and/or you don't get your fingers in the moving parts either!
