Set in new brushes , and polish the slip rings with some quite good sandpaper. Think about the brush holder. It should have two tiny holes in it, going through the rear of the alternator. Get a "adhere" to hold the brushes in. Some good "sticks": a toothpick, a straightend out paper clip, or the nozzle extender for the spray can, just like the a person they tape towards the aspect of a can of WD-forty.
