HELLLPPPPP !!!!!!!!!!!!!! i have a similar problem . But i cant post as yet
I am having a few problems with my 1999 komatsu pc220-lc6. i had a guy work on it and he messed up everything. i am now trying to troubleshoot and solve my problems .
1. today the machine decided not to respond to throttle inputs but revved fine manually when we go and push the throttle by the injector pump. it worked fine up to this morning .. we checked the throttle switch and it seemed to be working fine . we checked for continuity on it.. also i believe associated with this problem the machine wont shut off with the key and we would have to stall it . only started happening today .. could this be some sort of sensor on the pump / main valve system ?
2. the machine tracks very slow and weak unless i try to open the bucket which would be moving the right lever to the right position .. it just barely needs to be engaged to make the tracks move faster but it works and it makes a significant difference .
3. if you could give me some wiring and hydraulic diagrams of the machine that would be very good so i could trace all of my lines and make sure they are in the correct position since my ex- mechanic messed up all of our lines..
4. the machine gives off a error code E-02 .. i would go and verify this code in the morning ... i could also get more details about my machine like s/n if yall need it ! thanks a mill
