Was running my skid loader and then all of a sudden, the boom and bucket were locked up. Looked at the EIC and it shows LOC__. Got the dealer code to unlock the boom and tried that but EIC still reads the same. Installed new seat belt assy, no change. Have 12.8V at seat. When get in skid loader, EIC goes through its light check then comes back with the LOC__. Skid loader will start and run and move, but no boom or bucket. Run/Service switch is in the run position. Same behavior if I try the Service position. This is the older silver eic. Any ideas what might be going on? The manual I downloaded does not have the complete wiring diagram. Anybody have a copy they could scan and send to me? Thanks Kevin
