[Tinker]

Model A's and early flatheads work as a "live" system. The systems has current at all time. (less you use a battery shut off). If you take a battery charger and tap the lines together you always get a spark. Best way to read a spark/short is with a meter.


If I take a battery on the bench with 2 leads +/-. I'll get a spark almost every time I connect the leads... here again, I always wondered if there was truth to this tale.
