Unit will not throttle up. I have power coming into the throttle dial and coming out when I turn it to different positions. The book I got really doesn’t show if it goes to the machine controller first or the ecm? Just need a better schematic if anyone has one.
I have a machine with the same problem , let me know what you figure out .
Unable to accelerate, usually the throttle rotation is broken or the throttle motor is broken. Please check these two. The current flow of the excavator starts from the throttle pedal position sensor or throttle knob, passes through the controller, and finally reaches the engine control unit (ECM).
