Hey Folks, As always, thank you for your continued support and for reading this post. Here's the problem. We have a Daewoo 400-III hoe and after 30 minutes of running, the warning lights on the console start flashing and the engine drops down to idle. The console lights then return to normal except that the tach and the fuel guage, the guages on the lower half of the console, stop working. The engine continues to idle and that is all that it will do. We must then shutdown the engine, wait about 10 seconds and then start it up again. Then, everything is OK for another 30 minutes or so. Can any one tell me if this machine has error codes stored in the computer or what conditions would cause the motor to lock in at an idle? I have the service and parts manual for the machine and I have a strong background in electronics. Again, thank you for taking the time to read this post! Chris
Not familiar with Daewoo. Myself I would disconnect engine and or hydraulic temperature sensors and switches and see what happens. If it stops slowing the engine, start reconnecting sensors one at a time. You may be able to determine if there is a faulty sensor.
