My RV Alternators had three three amp 100 PIV diodes in each each unit. When a fuming customer returned for a warranty and I opened up the alternator and found all three blown to pieces...
"This unit saw reversed polarity"
"WHY..." sputter sputter "I installed it myself. And there is no way it was connected backward"
"That's a shame" I explained "Because if a customer admits a boo-boo I'll fix things at cost of parts"
Red Faced "I'll see you in court!"
30-years no court.
Maybe I've not seen-it-all but I am pretty certain I have seen most of it.
