T190 ser. 531615995 with intermitant "no hyd.functions and drive"

[wally69]

I have a late T190 ser. 531615995 with intermitant "no hyd.functions and drive"
when working code is none
when not working ACS light is on with codes:
32-04 ACS not comm. with bobcat controller
75-04 no comm.from drive controller
39-16 left joystick not connected
40-16 right joystick not connected
I have wiring schmatics and was doing pin-outs for powers and grounds and noticed voltage was a little high 15.1v
I unplugged alt. so now volts is about 12.2v but still "no hyd.and drive" and same codes
I changed the ACS controller a couple months ago for a "no drive" issue and put it back now to test but still
"no hyd.and drive" and same codes I now put back the new ACS controller.
It seems if it sits over night it will work for awhile.
any ideas wally 808-479-3323

Sounds like you have a loose or corroded wire connection somewhere in either plug to drive controller or to the main controller. Another possibility is partially broken wire in the harness. Loose or corroded power connection(s) can also have same results and codes - check fuse panel connections as well.
