I must admit, I do not understand this stator failure problem. I've been trying to glean a better understanding from all the posts and the article in the MOA mag.
My, admittedly uninformed bias has been toward an electronics failure..ie the regulator. the Stator is a lump of metal and some type of insulation polymer. It seems to me that it is so easy to design the stator to withstand over currents and over temps...with essentially no cost penalties....that is would be so dumb not to have huge design margins...it would not be the root cause.
Over my experience Iv've replace several regulators and a few alternator diodes....never had a stator problem. Yep I know this has no direct mean to this problem...but my bias is there till I understand the root cause.
Thanks for the additional info
