EX120-5 Excavator won’t go into hi speed

Revman · 2024-04-11 13:09

Hello, I have a 1995 EX120-5 that won’t go into hi speed, I think it might be a sensor issue because if the switch that automatically revs the engine up is on the motor will not rev up, it only happens on travel, every other function works fine, I am not sure where these sensors are located? Once and awhile it will work which also leads me to believe it’s a bad sensor or loose wire?
