Not sure if you've seen this but you may enjoy reading it.

It isn't due to the loads IMO, but rather the complexity of the charging program. That link takes 35 pages to describe a system that replaces an AVR. If any of the sensors fail it defaults to a 14.3 v charge voltage. One should hope that a sensor fails, IMO

Even Joseph "Prince of Darkness" Lucas managed to produce functioning AVRs.
