I have a TV380 that was operating well until we parked it for about a week. In that amount of time, the battery went flat and we jump started the machine. Since that took place, a 1905 code appears at start up. The machine will start and runs, but has no hydraulic functions. We have checked the fuses in the cab, the three 2 amp fuses in the engine compartment, replaced the battery, and removed, installed and checked the battery cables. Currently stumped and looking for opinions on where else to look or known issue areas involving the 1905 code. No other codes appear while running.
