I just bought a 1999 ram 1500 Sport last week. Ive notices that if i leave it sitting for few hours and start it it will start but after it turns over a few times. Recently I parked it at 2:30 AM Xmas eve and the next time i went to start it was 5:00 PM Xmas day, so it sat for 14 1/2 hrs and it would not crank, the battery was dead and i had t use my jumper. The battery is a Pro Start battery from pepboys and it has a sticker date of 7/16 so its New. I disconnected the negative and put the test light on the cable and touched the pen on the Neg. I then pulled fuses to see if any would kill the test light, nothing. The test light is pretty dim though so i figured its because of the PCM draw. Im stumped on what is killing the battery and wondered if there is anything that is common with the rams? What else can i try to see if its the truck or the battery? Any help would be appreciated.
