hey guys, sadly i am having more battery problems with my 16hp craftsman tractor that is around 24 or 25 years old. this is a newer battery, around a year or two old i believe. i hooked it up to a charger and it tested ok, however oncei hooked it up i got nothing. it originally came to my attention when i was getting ready to plow, started it up to let it warm up, it started, stalled, started then died. any suggestions? am i do for a new battery?
