    277c CTJWF00483 Thumb wheel will not operate on left Joystick

    Nige, Thank you so much for your technical assistance. It was great help. I had to purchase a new joystick from CAT. I am going to mail the other one in to see if it could get a new thumb wheel installed in it. It seems like a total waste to throw the whole joy stick in the trash because of...

    277c CTJWF00483 Thumb wheel will not operate on left Joystick

    So I have installed the wrong Joy stick on my machine. So will this joystick still have the same measurements? This would possible explain why I was having issues right away. When I contacted CAT after I installed the new stick they told me it was probably a different issue, not the joy stick.

    277c CTJWF00483 Thumb wheel will not operate on left Joystick

    This is my switch. Is it possible the PWM is in the ECM and just using this switch to generate the signal? I appreciate you and all your knowledge. Thank you. I am not a Forum person. You have made this a good experience.

    277c CTJWF00483 Thumb wheel will not operate on left Joystick

    I have a meter now that reads duty cycle. When key on and I have 5v from ground to signal. I then move my meter to duty cycle and there is nothing in center position/ forward or backwards. there are four wires to the roller switch would you know what the fourth wire does? If anything.

    277c CTJWF00483 Thumb wheel will not operate on left Joystick

    Would the thumb wheel give me a yellow triangle? The last time the switch went bad the yellow triangle never appeared. The switch just stopped working

    My meter does not measure frequency. I have 5v between pin 2 &3 at center position. The voltage does not change when thumb wheel is operated. I do not have duty cycle on my meter. I do Have just over 8v between pin 1 and 2
