Hi I am new to the web.
Can anyone help?
I have a Hitachi EX120-3 excavator year 1995.
I cannot get the engine to increase speed from the control panel “I,L,E,P or the increase button” and all of the LED’s will not come on. I removed and had a look inside and found a resistor bunted out.
The resistor that have gone is marked on the board as R2 and the only id number I can find on the board is YU-292 P (l).
Can anyone help with a technical drawing or can tell me what the value of the resistor should be and also what should be the voltage coming from the resistor. I measured the voltage coming to the resistor and it is 23 volts.
Thanks
