Hello, I have a 1984 Dodge ram 50 sport with the 4d55 turbo. I purchased it two weeks ago. It runs great and is very good condition as it sat in a barn for 10 plus years. I drove it for about a week and a half with out any issues. Then randomly one morning the battery was completely dead so I charged it and it started fine and ran fine. The next morning same thing the battery was dead again. I did the test to see if there was a short by testing it with a 12v tester and pulling fuses one by one, nothing changed throughout the entire test. I took the battery and got it tested and the battery is good. If anyone has any advice I would greatly appreciate it.
