Recently I corrected some oil spills that the main pump had, nothing internal, only rings and seals. The bomb was never opened at all. When the pump was installed again, the machine did not move properly and responded with lateral movements on its own. The two solenoids of the rear pump of another machine were replaced, it worked for a brief time, but it malfunctioned again. I think it's an electrical or communication problem, but I don't know what to do. Any help pleases
Are there any fault codes that come up on dash? Retrace all of the electrical wiring and connections make sure the connections are in t he correct position.
