Something to watch for when changing batteries. This is what happened on the first battery change on my 2006 D/A. Went to local battery dealer to have both changed. He disconnected one at a time. When complete I noticed that my engine hours had went to "0". I went to DieselPlace looking for answers but no one had an answer on what happened.
I always reference hours along with date and mileage when performing any maintenance. Fortunately I had just changed oil a few days before and knew the current mileage. For the remained of ownership I added the new hours to the old to get an accurate total f hours.
