Two problems related to battery have been reported for the 2003 Dodge Ram 2500. The most recently reported issues are listed below.
Tl- the contact owns a 2003 Dodge Ram 2500. The contact stated that while driving 45 mph, the vehicle began to lose power and the electronic control warning light illuminated. The vehicle then stalled with the illumination of the check engine and the overdrive warning lights. The contact disconnected and re-attached the battery. The vehicle was restarted and was able to be driven. The vehicle had not been diagnosed by a dealer or an independent mechanic. The failure and current mileages were 93,000. Kmj.
There is a persistent low voltage drain on the battery. It stays dormant for, at times, as long as 3 or 4 days without appearingand ranges from 1amp to 2 amps totally draining a otherwise almost brand new 8050 cold cranking apm International brand battery. Contacts in the doors and all major components have been disconnect in the debugging process. I already know of at least one other Dodge ram 1500 with the same symptoms. The battery has been replaced with a new one during the trouble shooting process. This is an intermittent issue which is proving to be very elusive. All systems that have been added on after market have been totally disengaged with no definitive result.
