Hey Everyone. I hope some of You can help me. I got an M320 engine control unit that has been burned due to overcurrent. there are 5 or 6 components which are impossible to identify. Could someone please send me a circuit schematic or a photo of this pcb ? i'm looking for the pcb of the unit with the sign "CATERPILLAR" on the picture.Thank You in advance
When I look at m320, I see 3116, no ECM, and C7.1, but in cab looks different. So..... Machine serial number would help. Engine serial number would help. ECM part number would help. Without at least one of the three above, it is impossible to find any info on that which you seek.
Sorry for the delayed answer. So. It is a Cat 315, that is all i know about the machine. I know, that these controllers were built in a lot of other machines too. Only a photo of the pcb would help a lot, but a schematic would be much better. Since we can't find a replacement, we have to repair the board ,but without knowing what to put there it's really hard.
Once again.....you have provided zero data to help source what you seek. First you say M320, then 315. Engine serial number is on top of engine. Machine serial number is on chassis. Ecm part number is on ecm housing. If you cannot provide at least one of the 3 above, no information can be researched. There are 33 (THIRTY THREE) different 315 machines, and, at least 7 different M320.
This is the only information i have about this part : https://avspare.com/caterpillar/monitor/1315196/
Well, you can source the updated part.
