I have a 773 bobcat that the auxiliary functions are only working one way. I checked fuses, previous owner replaced the coils on the control valve, I replaced switch on the right side handle due to the selonoid not receiving power when applied. It would only throw code 26-03. If I swap coils around the auxiliary works the opposite way so I think it is something electrical. What else should I check. Thanks
26-03 means that your front base solenoid has an error off, check the wiring around the top solenoids on the control valve. There should be only a 3/4 nut on both. If the wiring seems ok, OHM both out and compare the results. You can also swap them and see if you get a other code, for example a 27-03.
