starter check?

moparLeo,could you tell me why I would remove the batt. for charging?I,ve been working on these old things for a lot of years,never pulled batt. to charge.just pull the ground cable off batt. and put charger on.allways ready to learn something new,please alliterate:steering:.
You've been lucky. Luck does run out sometimes.
I never will forget these 2 examples... I worked for a tire/auto service store. The normal was to leave a customers battery on charger overnight and load test it next morning. Some would come in with battery in hand. Our charge and test might sell a battery.
We came in one morning to find battery acid all over the concrete floor. Out to the grocery store for several boxes of baking soda. Nice clean spot in the floor though. No more leaving the charger running overnight.
Then the 87or8 Thunderbird that came into the Ford store I worked at. A charger had boiled its battery. Looked like maybe they set the charger up on the engine using it for a hood prop. Battery tray and below, underside of hood, everything else in that general area was ate up bad!
