Thanks for your help. I installed another ECM this morning just for ha ha's and ended with the same result. Run for five minutes and died. I know it's not right to just throw parts at this problem, just wanted to appease my curiosity. My system is charging at 14.5V when running. Is there a possibility I am feeding 14.5 to the ECM and burning it out? What should the max voltage to ECM be?
