Ok I replaced the battery turned the key it cranked a couple of times sputtered a little and quit tried to start again and all it would was turn over like the battery was half dead. Recharged the battery same thing. Recharged the old battery same thing. The last thing I can try is charge both batterys connect them in parallel and see if that will turn it over at normal speed. just nobody freaks out parallel will be 12v but 2x the cranking amps.
