Squealing CRTs

Lead acid batteries can make spectacular short circuits. I
used to advise a group of students working on an HEV.
The battery voltage was 360V, I believe. A student managed
to short the terminals of the output of the main alternator
rectifier (connected directly to the battery) with some pliers.
The pliers fused at the joint and part of them was missing
entirely (vaporized?). The student had a couple of (minor) burns where
molten iron^H^H^H^H metal fell on him. It could have been worse;
fortunately, there were fuses that did blow.
