Maybe the generator is hungry. I had a pig that was squealing like your generator. I went to feed it, but I was out of its favorite food. It looked at the food I had set down, then it looked up at me again, then it stuck its head between my legs and threw me about four feet straight up and then proceeded to ram me with its serrated tusks all the way across its cage. Tore my pants and legs all up. It kicked the crap out of me, and he was supposed to be a pet. I found him in the yard when he was a baby.

I'd try feeding your generator a different brand of brushes. You might disconnect the main charging wire from the generator to see if it still squeals, maybe pull the brushes back and start it to see if it still squeals to make sure it's not something else inside that rubbing on something.

It is a definite NO-NO to put any type of lubrication on the commutator or brushes which must be always clean and dry. NO LUBRICATION. Regards, Kevin.
