Not an expert but here are two things to think about. Was the battery dead
or disconnected for a period of time before you picked it up? Could be just
an actual low voltage thing that might re-charge itself. Once in a great
while I find a fuse in the wrong slot, probably from people like me that
try to fix things by the seat of their pants. Good luck.
