My 614 was in storage for about three years due to the PTO self destruction. Replaced the PTO and checked the battery. Nothing. Put it on a charger with do results. While charger was on the lights worked well. Replaced the battery and nothing works now. No starter turnover, no lights. Nothing. Did the attempt to charge fry something. If so, what's the most likely damage: Flasher, Relay-Safety Interlick, or Solenoin Switch 4 Post. Anybody got a clue? Thanks.
