Hi all, hoping someone can help. I have a Komatsu PC75UU-2 excavator that has intermintently throw a code EE on the display. But machine has always turned over, it comes and goes and has generally run like a dream. Today, suddenly it threw the code as soon as i turned the key and it would not start. I check the batteries, one is 100%, the other was showing recharge which i am doing now. What is the cause of the EE code and would one of the two batteries being down at 606 cca be enough to stop it from starting?
