Had to move snow with my 504 yesterday when I turned tractor off it was like generator still wanted to spin. It was making a noise with the ignition off.I have a battery disconnect on all my tractors turned that off and generator stopped.What would cause this? THANKS dan

What do I do open it and try to clean it or replace? THANKS dan

A person may have some luck in cleaning/buffing/polishing the contacts on the cutout relay (one of the coil relays inside the Voltage Regulator) but do it gently as once all the shiny silvery coating is gone they can stick again. Its supposed to be open when shes setting not running (otherwise the genny draws current n spins like the DC motor it is) and be closed only when the genny is running and at higher then battery voltage. Id insure the VR has a good clean solid connection to case/frame ground often on the Generator body or elsewhere.
