Hello

Hoping for some pointers. Getting fault 404 on SCR drive: Open Armature Circuit. Have replaced contactor, checked all connections, checked motor, etc... Never happens in flight. Car always level with a floor and shut down. No entrapments. Happens every few days. Any help appreciated!

Contactor would be a good guess.
