I have a js 160 excavator. starts and runs. I have no hydraulics. I have 2 error codes. 135 2 stage = the 2nd stage relief solenoid is open circuited. and 139 cushion = the hard/soft cushion solenoid is open circuited. I ohm tested the solenoids and wires and the test good. I had service master4 pluged into the machine and it showed open circuits at the same 2 solenoids. Does anyone have any thoughts on what the problem could be? Thanks Silvax
Good day The most probable is the control lock out see attched. Kind regards Uffex
Without having a schematic specific to your machine, i offer a guess. A fault in the wiring, particularly a common to both solenoids, such as a ground . If you've access to the schematics, look for what's common between the two as a starting point. Good luck
Thank-you very much for your reply to my problem I will be sure to check both helpful suggestions and post my results. Thanks Silvax
if this is not resolved can i ask age of js please
