My 566 has not run since last year (no snowblowing this winter in Maryland!). When I went to start it and the battery was dead, I put it on the charger for a couple of days. Still wouldn't turn over. Jump started the Gravely with my other tractor (Kubota B7500 HST) and it started right up. As soon as I disconnected the jumper cable from the Kubota, the Gravely started to stall out. Clamped the jumper cable back on and the Gravely ran fine. Let it idle for a couple of minutes, disconnected the jumper cable, and it conked right out. I'm used to jump starting a car, when you get it running the electrical system runs off the alternator, plus re-charges the battery. Is this a similar situation with my 566? Is the alternator dead, as well as the battery? Any input would be greatly appreciated.
Sounds like the battery is stone dead..if you have a multi meter check it after charging...if you don't have a multi meter.bring it to a place that you would buy a new battery from...have them load test it....I am pretty sure that they will tell you that you need a new one...once a new one is installed I am pretty sure that it will go back to operating properly
