My truck sat about 3 months before we even started to touch it. Well we started to play with it finally got it all going and back on the road. When we got it back going we fired it up batterys was a little weak so we went down to autozone and got the most expensive battery we cold with 930 cranking amps. Well the battery not charging light is still on the truck and so it the battery light. The alternater is putting 14 volts back in the battery. It was coding for glowplugs but i figured that was because of a dead battery. Well its still codeing for glowplugs. I figure i would run the truck for a week or so and it will straighting up. Still same thing is happening. Any advice would be appericated
