Ok where to start? mmmmmm. . . . . . Just bought it last night. Plugged it in last night, This morning I had tried to start it. Low power. Charged batteries. Still the same. KC2006 came over. Looked at batteries, can't find culprit to why they would still be low on power. Took them to the store for check when KC left. 1 battery was bad. had to buy a new one. Put both batteries in. NOTHING!! No lights no power, or anything. This is my first diesel truck.
