All indications point to incorrect installation/fan rotation, but the third installation was by a separate mechanic, both shops couldn't get it wrong?
Where was the power supply picked up from? Could it be an over voltage/amperage situation?
Just thinking out loud fellas, go easy.
Alternator giving too much power,,,, then not enough,,,, if the brushes are only touching on the edges of the comutator
it can cause problems. I think a constant supply of power may be a factor.
What alternators do you normally us with a 6.5,
Interesting problem though
