From one moment to the next, only 3 and 4 work for me; 1 and 2 there is no force and I checked the 3 speed change valves, they are in an acceptable range but even so I have not been able to start I appreciate the help you can give me, regards Dagoberto M. Costa Rica
Welcome to HEF Dagomoyac . See the link below, Has an electrical schematic and a wiring diagram for a 310SG powershift transmission. @mg2361 for providing and @Tinkerer for the conversion . John Deere 310SG wont move I'll answer on your thread. HeavyEquipmentForums
good thanks for the scheme; I don't have 12 vdc in the 2nd coil and I gave it external voltage and I still don't see or feel that I connect the change, the 3 coils give me a good measure
Do you have ALL the proper voltage signals at the speed change switch outputs when selecting first or second gear ?
As soon as I can I will check again, I have it on the selector lever, down in coil 2 there is no voltage and I proceeded to feed 12 externally and even so, no change was seen only when 3 and 4 are selected. Regards and thanks
good to comment I already solved the problem it was not in the electrovalve it was between the coil and the connector there was a false contact when moving the cable I solved it by soldering said contact THANK YOU VERY MUCH FOR THE HELP AND THE DIAGRAM
