Diodes tend to fail shorted when overheated. So its a good chance that's
what is taking the fuse, though it could be a failure of a pass
transistor insulated mounting or a bad electrolytic filter capacitor. Or
the crow bar shorted or getting too sensitive and firing all the time

Probably 35 amps, 100 volts or greater PIV. About 1-1/8" square and a
