Hi,

I work in the Iveco workshop,and i´m having a problem with one Iveco Trakker.
The problem is with EDC ecu that has been burned 4 times in the same place in the circuit.
After mounting the new ecu the engine works fine,there is no faults in any ecu,but after let say 50miles the engine turned off and the EDC ecu has been burned.
I have checked all the wires for short circuit.
I have replaced one battery because was in short circuit.
Attached i have upload some foto of first burned ECU and the last burned ECU.
Sorry for my bad english

Maybe sometimes the power feed is up to 24v or shorted someone actuator or cable to the actuator.
Put extra stabilizer to the ecu power supply, see the wires to the actuators and put fuses to the actuators wires.
