Hello,
Please guide me , ECM P/N. 1448650 for Caterpillar Motor Grader S/N 5HM01522 , ESN. 6NC16223.
The unit can not operate, after an error welding procedure, where the ECM is not working.
I have opened the ECM, and I see there is a burning part.
I can not identify the component like the one in the photo.
Please help with information for the name of the part, specifications and where it is normally sold.
Thank for your attention.

That's a SMD (surface mount) tantalum capacitor, it's 22uF to 35v, it's found in electronics stores or damaged ECMs

Hi Roy Did replacing the cap fix the problem as i have one out of a D6 cat dozer done same thing from lightning strike we think,all output voltages to PWM,s were low so all pressures were low and so park brake only partially off and clutch,s only partially engaged.Replace it with a S/H ecm and works fine but still want to repair damaged one.
