Massive short?
Other plausible alternative is that there was a high resistance connection at each of those hollow terminals. Pulling high starting current across a high resistance connection will create a lot of heat that could have melted those hollow terminals. Power (i.e. heat) is P=I^2 * R = current (squared) x resistance So pulling something on the order of 100 amps to start across a seemingly small 2 ohm resistance ; Power (watts) = 100*100 * 2 = 20,000 Watts. |
