Thread: Alternator Diagram needed

  1. #1

    Alternator Diagram needed

    I have a R90s and am working on the alternator assy.

    It appears the brush holder is insulated where it mounts on the alternator "cover". But how? Is there a diagram showing the insulating washer(s)?

    thanks,

    Thank You Darryl,

    That confirms my suspicion, that only one brush is electrically isolated from the alternator cover/holder.

    Yes - the other brush is the ground path from the rotor to the engine case.
