Throttle control

[LASTWEST]

Has anyone had trouble with a Case trackhoe relating to the throttle control motor and/or the throttle potentiometer(throttle control )?
There is no response on the throttle knob--I have replaced the control motor and the throttle control potentiometer in the cab and still no luck. Fuses have been checked. The machine is a 1997 9030 B and has a computer. Thanks for any help.

Does the Case have the auto-idle on the right control lever..?? A push button deal on the end of the handle. Back in '98, I ran several different excavators during the cleanup of the big flood in Eastern Ohio... One being a new Case 9030. Can't remember if it was Case that had this feature, or John Deere.

Yes there is an idle button on the left hand control stick as I recall,that seems to be a reasonable assumption for a fault. Monday, I hope to talk to a serviceman to see where he directs me. I will keep you posted as to any encouraging finds, Thanks
