Hi all. I am new here and looking for some info. My dad bought a Wheel horse 417-A back in the 80's and never used it. He only used it to pull trailers around the yard. The tractor was given to me but it does not charge the battery. Can any one tell me what I might look for to resolve this situation? I did a search to avoid asking a question that has already been answered but came up empty. I will post pics when I figure out how. Thanks in advance.
