OH my goodness. I have a 753G machine with Key start on right and display on left. The lift, and tilt functions are not working. THe machine has foot pedals and they are locked! Sometimes when I start the machine it will display a code 18-07 (open circuit on spool lock solenoid), AND 02-17 (Hydraulic filter problem???? still not sure). Sometimes it will start and display no codes - all solid lights after hitting green button but no tilt or lift and pedals are still locked. I have applied 12v to the spool lock solenoids and they work and the pedals move. I have tested the harness when I turn the key and press green button and DO NOT have 12v coming from the harness. Does the signal come from the controller or does it go through a fusebox? I have traced some of the wires but do not want to destroy the loom at the moment if not needed. Does the controller have to get certain signals from other solenoids before it sends signals to the lock spools? What would the BCIS be checking in order to provide a code 18-07 and why might it come and go but the signal not be sent to unlock the spools? The lap bar and parking brake seam to operate correctly based off the display and lights when one or the other is operated. ANy help at this point would be great. All fuses and relays appear to be good. I am stuck and believing it is a controller problem but want to be sure.
