Are zap stoppers really needed on alternators?

Well, pardon me for asking you to address my question. In case you didn't
remember, since it always seems to slip your attention during your posts, I
wanted to know why the suppression is applied to the LOAD side of the
alternator diodes. Perhaps you two could stop slapping each others butts
long enough to try to answer that question.
True, there are none so ignorant as those who refuse to learn. Now that
we're even on stupid witticisms, can you try for a technical answer?
OK, I am going to try one more time. What I am about to say was
verified yesterday afternoon by Randy Johnson, formerly of Cruising
Equipment and developer of the Zap-Stop and confirmed by the tech
support people at Balmar and Leece-Neville.
When an alternator is producing a significant percentage of its capacity
to a load, be it a battery, motor or other device and that load is
suddenly removed the output voltage of the alternator will rise. While
the rectifier diodes can handle higher than normal amperage for short
periods they cannot tolerate voltages significantly over their rating
for even an instant. Therefore if this voltage rise is not checked
Sounds like they need to make them properly, with higher voltage diodes.
