Guys, I left the key switch on my JD on and ran the battery flat, thankfully it has been unseasonably warm recently so the fully discharged battery never froze. I have a charger on it right now, and am going to let it charge that way instead of starting it up immediately with the boost feature on the charger.
In the past I have read that the quickest way to ruin an alternator is to use it to recharge a dead battery, but what about the motorists who run their battery down and get a jump start, and then use the alternator to recharge the battery? Does a jump start actually put enough current into the run down battery so the alternator isn't damaged?
