Thanks Edward,
Recently, change from his original position both controllers. Left in right, right in left. An meke change, the line contactor don't turn off, and the motors work, but not in forward direction, at lease not in straigth position. All turned rigth or left, the forward direction works.
The trouble move on....
My opinion the SepEx 1244D-4491 have a internal short
The SepEx 1244D-4476 work fine.

Will be change the SepEx 4491 and tell you later.
Have you the service manual???
