Hi everyone, first off I want to mention I don't usually work on electric lifts but took on this job because I work on all of customers IC lifts. I have a Raymond stand up model easi dr 25tt ser: et d 03 1215. I recently replaced joystick due to no drive. Now problem is after self test start up, unit would reach on its own without operator standing in station. You'll heard control valve solenoid click and you can see hoses for reach on mast " move" coz of fluid flowing. I also don't have tilt or side shift functions. There's constant power to solenoid coil on hyd control valve. I thought it was the aux module since that's the common thing all functions have. Installed new card, aux functions worked for 30 seconds, then reach extended out again on its own. I don't have a manual for this lift but and pointers would be much appreciated. Thanks in advance
