Q: My battery was tested and when I jump it the truck starts, take them off and it dies instantly.
My sister drove my truck to work at 730 am, she went to start it and it wouldn't start at all. We jumped it with her car, started just fine, took one jumper off the battery and died instantly. I was thinking it was the connectors to the terminal. I know the alternator is good because it ran fine this morning and last night. Autozone said it could be some alternator fuse but who knows. Any advice helps.
