Are zap stoppers really needed on alternators?

Depending on standard, load dump on 12 volts can be 60 volts or as high as 270 volts. Two standards are SAE J1455 and ISO 7637-1. As Glenn has accurately described, load dump can be created by disconnecting a major load from alternator - such as battery. 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. snip 'Cause the average user won't be able to install a system inside the alternator case? Further, it don't matter much, 'cause the 1/2 cycle of foreward output overvoltage current sinked via zapstopper is sufficient to load out all the overvoltage current generated by the no longer energised field as it collapses? -- Terry K - My email address is MY PROPERTY, and is protected by copyright legislation.
