I moved my battery to the trunk a few years ago and now for some reason my battery want stay charged like I have a short or something. I tried to jump it off today and as long as the jumper cables work hooked up my car would run. As soon as I took them off it died and the cables were very hot. They were only on for maybe 30 secs. Does this sound like a short in the battery cable from battery to starter solenoid or could it be a short somewhere else? Thanks for any help
