Re: 4310 won\'t go, engine and hydr OK.
Problem solved!!! friend came over and hooked up a fancy e-machine, said coil is testing good, still could be valve itself though, but doesn't make sense cause it can't 'talk' back to computer. said we should try re-calibrating again. he read procedure and asked me all the questions and when we came to 'motion match switch must be off' i said i don't know, cause my motion match switch is different than the book, i only have one that has a fast and slow, i don;t have the one upper left that has a lock symbol and max symbol. i assumed (the problem) that mine didn't have an off, so i had left it in the upper or decel faster position. he thought that the lower or slower decel postion might be off cuase it's not 'making' the tractor slow faster. we tried it in the lower position for the re-cal this time. this time it wnet through all as before but this time at the end THE CODE WENT AWAY after the last test. yahooooo. tractor now works properly. soooooo we are guessing on what cuased the problem in the first place and the ony thing we can come to is the rear proportional valve coil wire (purple) was stretched enough to break it momentarily but the first thing i did when i saw it was move it away from the suspect break arm and i may have re-completed the circuit. then when i tried to re-cal i had the motion switch in the wrong place and just could could complet the re-cal which then shut the whole system down. if it happens again, we will go right to the suspect wire. advice: we all should get under our tractor now and then and check that the wires are all out of harms way, my tractor has 200 hrs on it but maybe going over all the trees and brush that i do moved/stretched a wire enough to cause this whole saga.
