Ford 5000 Tractor we were trying to jump start yesterday. Battery had been in it since Moses played fullback for Jerusalem.
Crank it and cranked it and cranked it. Bastard would not fire. Took the inadequate leads off for a moment to let them cool off. Noted funny smell coming from battery on tractor.
Shouldve known better, as the song goes...but we tried to put the leads back on the battery didnt we???
One small spark and BOOM!! Not just a small one either...a real, ringing in the ear boom.
Not to mention myself and the bloke that attempted to put the leads back on got hot acid in our faces. Washed that off very very quickly and had a look at the battery.
Half the top completely blown off!!!
Lesson learnt...wont be doing that again in a hurry...
