I just thought I would bring this question here, just in case someone might know an answer. So I bought this old truck for yard work. It was running like a champ. My nephew came over to visit, he is a proud new mechanic btw, LoL. He was like cool truck can I check it out. He dinked around with it a bit and started it up. When he turned the truck off, he didnt turn the key all the way off. It drained the battery, not completely but enough that it wouldnt start.
I charged it, and it started up. I was able to drive to drop off a load of branches to the wood recycling place, and back. I thought well problem solved. But the next time I went to start it, no go. Same story on repeat.
So basically the battery wont hold a charge now. Yesterday I charged it in the morning, but didn't drive it. I tried to start it again later that evening and it was dead again. I am wondering if anyone might know something?
I know that it is possible that the battery was damaged and wont hold a charge, or it could be that maybe there was too much stress on the alternator and it is not charging. But the thing is when I start it after jumping the gauge indicates that it is charging fine. I guess my next step would be to go get the battery tested, and then the alternator.
But I thought one of you might know something that I am missing in my little mystery.
