How to repair vacuum cleaner electric motors brushes that spit fire (sparks)?
Question: I tried to clean carbon residue from the commutator and added pressure to the brushes, but could not solve the problem. Could the problem be the old brushes? I wonder if new brushes will do the trick. Sparking continues and carbon residue builds up within seconds.
