Well Jim I felt like leaving but since I had a month more of on the road in 90+ heat I bit my tongue and paid the price.
There is a small plate on the back of the gen where the fins are. Take it off and remove the brushes. (put them in a rag so they don't touch each other with the wires still connected).
You will see the stator/slip rings (it's a wheel). Take a pair of needle nose pliers and use a piece of fine sand paper to place against the stator and press the start button to spin the stator. A few spins will clean it up. Just make sure the brushes aren't touching each other or a ground.
It's pretty simple but hard to explain. Here is something I found on the net:
Q. Why do the generator’s slip rings require cleaning periodically?
A. During periods of storage and a lack of regular exercise, RV generator slip rings can become corroded, particularly in areas near salt water. Even with regular running, a layer of oxide and brush residue can build up on the rings, increasing
their electrical resistance. Proper cleaning (such as with the Slick Stick Slip Ring Cleaning Tool, available from Flight Systems) restores the running surface to like-new condition. This results in cooler running as well as extended brush
and regulator life. Dirty slip rings can cause overheating and premature regulator failure.
Q. How can I determine if the slip rings need to be cleaned?
A. A quick visual inspection can be done by looking through the cooling slots at the rear of the generator with a bright light. The slip rings should appear as shiny clean metal. You can also unplug the regulator and measure the resistance between pins 9 and 10 of the plug that was connected to the regulator. If this reading is greater than 28 ohms, cleaning is needed.
