cat motor with 200 hrs running fine then all of sudden loses compression in 3 cly why
How do you know it’s low compression? Any error messages?
It could be a software error, sensor fault, or something seriously wrong, I could make up some things that might cause this, but I have absolutely no way of knowing what happened here 🙂
First, make 100% sure what the problem is, record all the error codes/messages. Does it run at all?
