Hey guys, I have an electrical issue I need some guidance on. I went to run the tractor for the first time this year and found that the battery was dead. I put the charger on the battery and after an hour or so, got the tractor to fire up. After a little warm up time, I started mowing. When I engaged the pto, the ammeter showed a discharge of the battery. I continued to mow for about 15 minutes and then shut off the pto, to get off the mower without cutting my toes off. When i got back on, the PTO would not engage and the ammeter was still showing a slight discharge. I drove it back in the garage and shut it down. I tried starting a little later and couldn't even get a click. So i am pretty sure that the battery is shot, but would this cause the PTO to not start up as well? I haven't had time to do any other investigation, but since the engine was running and the ammeter still showed a discharge, i am thinking that there is something more going on. I am going to get a new battery this weekend, but past that...how do i debug if I am still showing a discharge?
Thanks!
