The last 6 months or so I've been getting alot of CEL's. I just figued it was emission related problems. After reading forms here, I learned how to do the key trick to check codes. I got a P2509.. Thanks to Mopar1973Man he told me the code was (ECM-intermitton power). I called the dealer today, they said Cummins recomended fix was to clean & inspect ground wires/cables. I'm taking it in wednesday to let them work on it. Man this will be nice if this is a fix. Has anyone else had anyting like this.

 

GOOD LUCK i hope your issue is fixed

 

Got a new Battery, said volts were good but amps bad, see how this goes
